7桥梁垮塌事故
超 载 !
黑龙江铁力市西大桥发生压塌
2009年6月29日2时30分 左右,黑龙江省铁力市 西大桥发生垮塌事故, 截至上午10时55分,已 从事故现场发现落水车 辆8台;救出落水人员18 人,其中4人受伤,重伤 1人经抢救无效死亡. 初步认定事故原因为超 载
津晋高速匝道桥倒塌
造成6人死亡,7人受伤的"715"津晋高速匝道桥倒塌事故 直接原因已经查明. 根据交通运输部和国家安全监管总局联合专家 组调查,综合分析,事故的直接原因是:在单车道的A匝道桥上, 为避让前方逆行车辆,3辆严重超载车辆密集停置并偏离行车道, 车辆外轮距离右侧护栏内缘小于1米,从而形成巨大偏载,导致桥 梁梁体向右侧倾斜而引起桥梁倒塌.
一只安徽霍邱籍货船沿通吕运河行至海门市境内的国强大桥下 时,船头猛然撞到桥梁上发出惊天响声,货船被牢牢卡在桥下动弹不 得.海门市交通,海事等部门人员立即赶到现场,迅速将困在船上的 3名船员救出.经技术鉴定,被撞后的大桥两侧龙骨脱落,桥面仅靠 货船支撑.
2008年3月27日, 舟山金塘岛与宁波镇海间的灰鳖洋海域,东经 121度47分,北纬30度03分."勤丰128"货轮是在27日零时左右驶离 宁波港的,估计货轮是从秦皇岛运煤到镇海,原打算前往天津港, 不料在1时15分北上途中撞上金塘大桥靠近金塘岛一侧,主通航孔以 西1.5公里的非通航孔桥面部分.船杆撞到了桥梁,致使桥面塌落并 砸向货船.
洪水冲垮桥梁
2008年8月2日零时18分,辽宁公路局接到营口市防汛抗旱指 挥部通报,强降水形成的洪水冲塌了位于黑(河)大(连)公路 (202国道)上的熊岳大桥,致使大桥3孔坍塌. 据营口市有关部门介绍,可能有一辆小轿车坠入桥底,车内 约有2人,另有一小型货车卡在桥面断裂处,现已经落在坍塌的 桥板上,车上2人没有受伤.

PBL剪力键应用与研究综述
PBL剪力键应用与研究综述摘要：本文对一种新型抗剪连接件——PBL剪力键的应用发展概况和构造形式、承载力影响因素和计算公式进行了分析和总结，为PBL的研究和应用提供一定的参考。
关键词：PBL剪力键、承载力、综述1、引言抗剪连接件是将钢梁与混凝土板组合在一起共同作用的关键部件，其主要作用有两个：一是用来承受并传递钢梁与混凝土板间的纵向剪力；二是用来抵抗混凝土板与钢梁之间的掀起作用。
抗剪连接件形式较多，按照变形能力可分为刚性连接件和柔性连接件两类。
柔性连接件刚度小，作用在钢-混凝土界面的剪力会使其变形，界面发生滑移时，抗剪连接件的承载力不会降低，组合梁的剪力发生重分布。
常用的柔性抗剪连接件有栓钉、弯筋、槽钢等。
方钢、马蹄型钢等连接件属于刚性连接件，型钢连接件容易在周围的混凝土内引起较高的应力集中，常用于不考虑剪力重分布的结构中。
PBL是近几十年出现的一种新型剪力连接件，如图1.1所示。
在钢梁翼缘板上沿纵向焊接开孔钢板，浇筑混凝土后，孔中的混凝土榫可以抵抗钢-混界面的剪力流，可根据抗剪需要，在孔中穿钢筋来加强其抗剪承载力。
2、PBL剪力键的应用与发展概况PBL一词源于德文Perfobond Leiste，英文为Perfobond Strips（PBS），中国文献中一般称为PBL剪力键。
PBL剪力键最早出现于20世纪80年代，德国斯图加特大学Otto-Graf学院在一组合梁的上翼缘纵向焊接开孔钢板，为PBL的雏形。
随后德国Leonhardt教授和Partners公司研究开发了该种新型剪力键，并将其应用于委内瑞拉的Caroni河桥上。
同时，日本学者也对PBL进行研究，将应用于桥塔钢-混结合段处的剪力连接器中。
此后，PBL剪力键多应用于波形钢板与混凝土顶板的连接上，在日本的高架桥中应用广泛。
我国对PBL的研究和应用时间较晚，学者雷昌龙对应用了PBL剪力连接器而取消钢梁上翼缘的组合梁进行推出试验和疲劳试验研究，结果表明剪力键仍起作用，这种构造形式可以减少用钢量，而其抗疲劳性能优良。

安全标准规定的普通照明用led灯具上的标志图文
安全标准规定的普通照明用LED灯具上的标志武汉长江半导体照明科技股份有限公司方和全 201302261前言标志是电气类产品设计安装使用时的一项必要安全措施, 是对由于技术上和经济上无法根除的残余危险的一种有效警告, 也是确保产品达到预期使用功能的一项重要措施。
此外, 标志也是国家相关产品质量的法律要求，绝对不能掉以轻心。
用LED作光源的灯具，仍然是灯具。
灯具应设计和制造得使其在正常使用时能安全地工作，对人或周围环境不产生危险。
LED照明灯具作为灯具中的一种，首先要符合灯具的安全要求，其次才是满足LED灯具的专有技术指标。
灯具上的标记指印制或刻制或粘贴贴在灯具上的标记, 即行业内常说的灯具铭牌、灯体标或主标贴、灯头标、功率标和瓦特标等相关内容。
灯具的标志关系到安全，许多跨入LED以及LED灯具行业的新厂商，却对灯具安全标准和对灯具标志的要求知之甚少，或因标准分散而理解不全，甚至对标准知而不办，成为“三无”产品的来源，结果可能导致的安全后果将不堪设想。
据文献[1]的数据，2008年做的460批灯具型式试验的不符合项数统计,标志存在的问题占到全部不符合项的54.1%, 标记有问题的灯具到达23.17%。
还有许多没有经过安全认证的产品，以为可以“自我宣称”，也将安全认证标志印在产品上，拉大旗作虎皮，混淆视听，也是对安全的忽视，同样会导致严重的安全后果。
本文按已有的国家标准尤其是国家强制性标准，对有关普通照明用灯具的铭牌（灯体标、主标贴）上有关安全的标志和要求作了梳理汇集，期望得到对LED灯具标志的项目、位置、尺寸和质量的清晰答案。
对其它必不可少的标志但可在说明书、安装指导文件中说明的文字和图案，以及包装物上的标志另外再述。
2 与强制性标志相关的安全标准如果说推荐性标准是指导性的可以有所选择，但强制标准则必须不折不扣的执行。
LED灯具有了下列一些专门的强制性标准且基本等效采用IEC标准：GB 19510.1-2009/IEC61347-1：2007灯的控制装置第1部分：一般要求和安全要求；GB 19510.14-2009/IEC61347-2-13：2006 灯的控制装置第14部分：LED模块用直流或交流电子控制装置的特殊要求；GB 24819-2009/IEC62031：2008普通照明用LED模块安全要求；GB 24906-2010/(IEC62560:2011)普通照明用50V以上自镇流LED灯安全要求；GB 19651.3-2008/ IEC60838-2-2:2006杂类灯座第2-2部分：LED模块用连接器的特殊要求；GB7000/IEC60598灯具GB7000是对灯具总体安全要求的强制性系列标准。

DAC081C081_08中文资料
March 13, 2008 DAC081C081/ DAC081C0858-Bit Micro Power Digital-to-Analog Converter with anI2C-Compatible InterfaceGeneral DescriptionThe DAC081C081 is an 8-bit, single channel, voltage-output digital-to-analog converter (DAC) that operates from a +2.7V to 5.5V supply. The output amplifier allows rail-to-rail output swing and has an 4.5µsec settling time. The DAC081C081 uses the supply voltage as the reference to provide the widest dynamic output range and typically consumes 132µA while operating at 5.0V. It is available in 6-lead TSOT and LLP packages and provides three address options (pin se-lectable).As an alternative, the DAC081C085 provides nine I2C ad-dressing options and uses an external reference. It has the same performance and settling time as the DAC081C081. It is available in an 8-lead MSOP.The DAC081C081 and DAC081C085 use a 2-wire, I2C-com-patible serial interface that operates in all three speed modes, including high speed mode (3.4MHz). An external address selection pin allows up to three DAC081C081 or nine DAC081C085 devices per 2-wire bus. Pin compatible alter-natives to the DAC081C081 are available that provide addi-tional address options.The DAC081C081 and DAC081C085 each have a 16-bit reg-ister that controls the mode of operation, the power-down condition, and the output voltage. A power-on reset circuit ensures that the DAC output powers up to zero volts. A power-down feature reduces power consumption to less than a microWatt. Their low power consumption and small packages make these DACs an excellent choice for use in battery op-erated equipment. Each DAC operates over the extended industrial temperature range of −40°C to +125°C.The DAC081C081 and DAC081C085 are each part of a fam-ily of pin compatible DACs that also provide 12 and 10 bit resolution. F or 12-bit DACs see the DAC121C081 and DAC121C085. For 10-bit DACs see the DAC101C081 and DAC101C085.Features■Guaranteed Monotonicity to 8-bits■Low Power Operation: 156 µA max @ 3.3V■Extended power supply range (+2.7V to +5.5V)■I2C-Compatible 2-wire Interface which supports standard (100kHz), fast (400kHz), and high speed (3.4MHz) modes ■Rail-to-Rail Voltage Output■Very Small PackageKey Specifications■Resolution8 bits ■INL±0.6 LSB (max)■DNL±0.1 LSB (max)■Settling Time 4.5 µs (max)■Zero Code Error+10 mV (max)■Full-Scale Error−0.7 %FS (max)■Supply Power—Normal380 µW (3V) / 730 µW (5V) typ —Power Down0.5 µW (3V) / 0.9 µW (5V) typ Applications■Industrial Process Control■Portable Instruments■Digital Gain and Offset Adjustment■Programmable Voltage & Current Sources■Test EquipmentPin-Compatible AlternativesAll devices are fully pin and function compatible.

Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Operation of the device beyond the maximum Operating Ratings is not recommended.Note 2:All voltages are measured with respect to GND = 0V, unless otherwise specified.Note 3:When the input voltage at any pin exceeds 5.5V or is less than GND, the current at that pin should be limited to 10 mA. The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 10 mA to two.Note 4:The absolute maximum junction temperature (T J max) for this device is 150°C. The maximum allowable power dissipation is dictated by T J max, the junction-to-ambient thermal resistance (θJA ), and the ambient temperature (T A ), and can be calculated using the formula P D MAX = (T J max − T A ) / θJA . The values for maximum power dissipation will be reached only when the device is operated in a severe fault condition (e.g., when input or output pins are driven beyond the operating ratings, or the power supply polarity is reversed).Note 5:Human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor. Machine model is a 220 pF capacitor discharged through 0 Ω. Charge device model simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated assembler) then rapidly being discharged. 8D A C 081C 081/ D A C 081C 085Note 6:Reflow temperature profiles are different for lead-free packages.Note 7:The inputs are protected as shown below. Input voltage magnitudes up to 5.5V, regardless of V A , will not cause errors in the conversion result. For example, if V A is 3V, the digital input pins can be driven with a 5V logic device.30052304Note 8:To guarantee accuracy, it is required that V A and V REF be well bypassed.Note 9:Typical figures are at T J = 25°C, and represent most likely parametric norms. Test limits are guaranteed to National's AOQL (Average Outgoing Quality Level).Note 10:This parameter is guaranteed by design and/or characterization and is not tested in production.Note 11:Spike suppression filtering on SCL and SDA will supress spikes that are less than 50ns for standard-fast mode and less than 10ns for hs-mode.Note 12:Applies to the Multiplying DAC configuration. In this configuration, the reference is used as the analog input. The value loaded in the DAC Register will digitally attenuate the signal at Vout.Note 13:C b refers to the capacitance of one bus line. C b is expressed in pF units.Specification DefinitionsDIFFERENTIAL NON-LINEARITY (DNL) is the measure of the maximum deviation from the ideal step size of 1 LSB,which is V REF / 256 = V A / 256.DIGITAL FEEDTHROUGH is a measure of the energy inject-ed into the analog output of the DAC from the digital inputs when the DAC output is not updated. It is measured with a full-scale code change on the data bus.FULL-SCALE ERROR is the difference between the actual output voltage with a full scale code (FFFh) loaded into the DAC and the value of V A x 255 / 256.GAI N ERROR is the deviation from the ideal slope of the transfer function. It can be calculated from Zero and F ull-Scale Errors as GE = FSE - ZE, where GE is Gain error, FSE is Full-Scale Error and ZE is Zero Error.GLITCH IMPULSE is the energy injected into the analog out-put when the input code to the DAC register changes. It is specified as the area of the glitch in nanovolt-seconds.INTEGRAL NON-LINEARITY (INL) is a measure of the de-viation of each individual code from a straight line through the input to output transfer function. The deviation of any given code from this straight line is measured from the center of that code value. The end point method is used. INL for this product is specified over a limited range, per the Electrical Tables.LEAST SIGNIFICANT BIT (LSB) is the bit that has the small-est value or weight of all bits in a word. This value isLSB = V REF / 2nwhere V REF is the supply voltage for this product, and "n" is the DAC resolution in bits, which is 8 for the DAC081C081.MAXIMUM LOAD CAPACITANCE is the maximum capaci-tance that can be driven by the DAC with output stability maintained.MONOTONICITY is the condition of being monotonic, where the DAC has an output that never decreases when the input code increases.MOST SIGNIFICANT BIT (MSB) is the bit that has the largest value or weight of all bits in a word. Its value is 1/2 of V A .MULTIPLYING BANDWIDTH is the frequency at which the output amplitude falls 3dB below the input sine wave on V REFIN with a full-scale code loaded into the DAC.POWER EFFICIENCY is the ratio of the output current to the total supply current. The output current comes from the power supply. The difference between the supply and output cur-rents is the power consumed by the device without a load.SETTLING TIME is the time for the output to settle to within 1/2 LSB of the final value after the input code is updated.TOTAL HARMONIC DISTORTION (THD) is the measure of the harmonics present at the output of the DACs with an ideal sine wave applied to V REFIN . THD is measured in dB.WAKE-UP TIME is the time for the output to exit power-down mode. This time is measured from the rising edge of SCL during the ACK bit of the lower data byte to the time the output voltage deviates from the power-down voltage of 0V.ZERO CODE ERROR is the output error, or voltage, present at the DAC output after a code of 000h has been entered.DAC081C081/ DAC081C085Transfer Characteristic30052305FIGURE 1.

The code loaded into the DAC register determines which switch is closed, connecting the proper node to the amplifier. The input coding is straight binary with an ideal output voltage of:V OUT = V REF x (D / 256)where D is the decimal equivalent of the binary code that is loaded into the DAC register. D can take on any integer value between 0 and 255. This configuration guarantees that the DAC is monotonic.30052307FIGURE 3. DAC Resistor String1.2 OUTPUT AMPLIFIERThe output amplifier is rail-to-rail, providing an output voltage range of 0V to V A when the reference is V A . All amplifiers,even rail-to-rail types, exhibit a loss of linearity as the output approaches the supply rails (0V and V A , in this case). For this reason, linearity is specified over less than the full output range of the DAC. However, if the reference is less than V A ,there is only a loss in linearity in the lowest codes. The output capabilities of the amplifier are described in the Electrical Ta-bles.The output amplifiers are capable of driving a load of 2 k Ω in parallel with 1500 pF to ground or to V A . The zero-code and full-scale outputs for given load currents are available in the Electrical Characteristics Table.1.3 REFERENCE VOLTAGEThe DAC081C081 uses the supply (V A ) as the reference.With that said, V A must be treated as a reference. The Analog output will only be as clean as the reference (V A ). It is rec-ommended that the reference be driven by a voltage source with low output impedance.The DAC081C085 comes with an external reference supply pin (V REF ). For the DAC081C085, it is important that V REF be kept as clean as possible.The Applications section describes a handful of ways to drive the reference appropriately. Refer to Section 2.1 for details.D A C 081C 081/ D A C 081C 0851.4 SERIAL INTERFACEThe I2C-compatible interface operates in all three speed modes. Standard mode (100kHz) and Fast mode (400kHz) are functionally the same and will be referred to as Standard-Fast mode in this document. High-Speed mode (3.4MHz) is an extension of Standard-Fast mode and will be referred to as Hs-mode in this document. The following diagrams de-scribe the timing relationships of the clock (SCL) and data (SDA) signals. Pull-up resistors or current sources are re-quired on the SCL and SDA busses to pull them high when they are not being driven low. A logic zero is transmitted by driving the output low. A logic high is transmitted by releasing the output and allowing it to be pulled-up externally. The ap-propriate pull-up resistor values will depend upon the total bus capacitance and operating speed.1.4.1 Basic I2C ProtocolThe I2C interface is bi-directional and allows multiple devices to operate on the same bus. To facilitate this bus configura-tion, each device has a unique hardware address which is referred to as the "slave address." To communicate with a particular device on the bus, the controller (master) sends the slave address and listens for a response from the slave. This response is referred to as an acknowledge bit. If a slave on the bus is addressed correctly, it Acknowledges (ACKs) the master by driving the SDA bus low. If the address doesn't match a device's slave address, it Not-acknowledges (NACKs) the master by letting SDA be pulled high. ACKs also occur on the bus when data is being transmitted. When the master is writing data, the slave ACKs after every data byte is successfully received. When the master is reading data, the master ACKs after every data byte is received to let the slave know it wants to receive another data byte. When the master wants to stop reading, it NACKs after the last data byte and creates a Stop condition on the bus.All communication on the bus begins with either a Start con-dition or a Repeated Start condition. The protocol for starting the bus varies between Standard-Fast mode and Hs-mode. In Standard-Fast mode, the master generates a Start condi-tion by driving SDA from high to low while SCL is high. In Hs-mode, starting the bus is more complicated. Please refer to section 1.4.3 for the full details of a Hs-mode Start condition.A Repeated Start is generated to either address a different device, or switch between read and write modes. The master generates a Repeated Start condition by driving SDA low while SCL is high. Following the Repeated Start, the master sends out the slave address and a read/write bit as shown in Figure 4. The bus continues to operate in the same speed mode as before the Repeated Start condition.All communication on the bus ends with a Stop condition. In either Standard-Fast mode or Hs-Mode, a Stop condition oc-curs when SDA is pulled from low to high while SCL is high. After a Stop condition, the bus remains idle until a master generates a Start condition.Please refer to the Phillips I2C® Specification (Version 2.1 Jan, 2000) for a detailed description of the serial interface.30052311FIGURE 4. Basic Operation.1.4.2 Standard-Fast ModeIn Standard-Fast mode, the master generates a start condi-tion by driving SDA from high to low while SCL is high. The Start condition is always followed by a 7-bit slave address and a Read/Write bit. After these eight bits have been transmitted by the master, SDA is released by the master and the DAC081C081 either ACKs or NACKs the address. If the slave address matches, the DAC081C081 ACKs the master. If the address doesn't match, the DAC081C081 NACKs the master. For a write operation, the master follows the ACK by sending the upper eight data bits to the DAC081C081. Then the DAC081C081 ACKs the transfer by driving SDA low. Next, the lower eight data bits are sent by the master. The DAC081C081 then ACKs the transfer. At this point, the DAC output updates to reflect the contents of the 16-bit DAC reg-ister. Next, the master either sends another pair of data bytes, generates a Stop condition to end communication, or gener-ates a Repeated Start condition to communicate with anotherdevice on the bus.For a read operation, the DAC081C081 sends out the uppereight data bits of the DAC register. This is followed by an ACKby the master. Next, the lower eight data bits of the DAC reg-ister are sent to the master. The master then produces aNACK by letting SDA be pulled high. The NACK is followedby a master-generated Stop condition to end communicationon the bus, or a Repeated Start to communicate with anotherdevice on the bus.DAC081C081/ DAC081C085。
