一中科技实验楼结构设计

摘要

本设计为一中科技实验楼，为五层框架结构。建筑总高度为19.5m，建筑面积为4201.15mm2，室内外高差为0.45mm，本地区抗震设防烈度为8度，框架的框架等级为二级。首先根据提供资料及框架结构的优点确定框架布局及承重方案。再根据承重方案选择、构件截面尺寸选择、重力荷载代表值计算及横向框架侧移刚度计算确定所设计框架为规则框架体系。然后计算了水平地震荷载作用下一榀框架的内力分析并求出内力，做出内力图，计算竖向荷载(恒载、活载)作用下各杆端内力，用二次分配法进行内力分配，接着内力组合，找出最不利的一组或几组来进行构件截面设计。最后，用计算机软件（PKPM）对一榀框架进行计算，并绘制了楼板的配筋图等。

Technology lab building in the NO.1 middle school of xxxxxx

Abstract

The design is technology lab building for the five-story frame structure in the NO.1 middle school of xxxxxxxx . The total building area is about 4201.15square meters and the total building height is 19.5 meters, and the difference between inside and outside ground

levels is 450 millimeter. The seismic fortification intensity design is 8 degrees, the class of frame structure is Second class.First according to the design matcrial which provides ,as well as the merits of the framework of layout and loading programs. Under the program then loading the choice beam size choices, gravity loads on behalf of the calculation of horizontal and lateral stiffness framework of the calculation to determine the framework for the design rules framework. Then calculate the horizontal seismic loads framework of the next load analysis and internal forces sought forces, internal forces made plans, calculated vertical load (constant load, live load) under the rod ends with the internal force secondary distribution method for internal force distribution, Then internal force composition, identify the most disadvantaged group or a few groups to beam design. Finally, the computer software (PKPM) carries on one frame to match the muscle chart,the floor matches the musclechart as well as the staircase matches the muscle chart the structure to leave the chart .

Key words: frame structure; office building design;section design；

internal force combination；moment distribution method
