1.This command will export out a model in a Perform3D Structure formatted file using the
following transfer rules.
这个命令能够按以下转换规则导出Perform3D结构格式文件。

2. Units are transferred according to the current program units.
转换的单位以现有sap2000模型为准。

3. Only concrete/steel/rebar materials are transferred. If a concrete/steel/rebar material does not exist, a default one is automatically created during the transfer.
For uniaxial/anisotropic materials, the first set of properties are used as an isotropic material (E, Nu, G).
The following Perform3D Materials are generated based on model material types and are used in the corresponding components:
Inelastic Steel Material, Non-Buckling
Inelastic Concrete Material
Inelastic Shear Material for a Wall
Elastic Material for Fiber Sections
Elastic Shear Material for a Wall
Elastic Material for a Slab or Shell
只有concrete/steel/rebar这三种材料能够转换。

如果sap2000建的模型没有concrete/steel/rebar，Perform3D会按照默认的材料属性自动赋予结构。

在模型的材料类型中，以下Perform3D材料生成并用来合成构件。

非弹性钢材，无屈服的
非弹性混凝土材料
纤维截面弹性材料
墙体弹性剪切材料
板或壳弹性材料
4. Frames are transferred into different Perform3D Frame Member Compound Components. Depending on the material, geometry, end releases, and hinges assigned,
Elastic or FEMA beam/column compounds are defined and used for frame members.
框架被转换成Perform3D里的Frame Member Compound Components。

根据材料，几何，端部释放及铰的指定，弹性或FEMA梁/柱构件被定义或用来形成框架构件。

Important:
Frames with hinges are transferred based on their geometry (i.e. vertical = column, horizontal = beam, other = brace)!
Perform3D Inelastic FEMA beam/column M-phi capacity/PMM capacity values need to be input by the user!
Frame section modifiers are not transferred.
Frame offsets and insertion points are not transferred.
Link types other than hinges, such as isolators/dampers, are not transferred.
注意：
框架的铰根据其几何属性来转换（竖向的是柱铰，水平的是梁铰，而其他的是支撑的铰）
Perform3D非弹性FEMA梁/柱构件，pmm铰值需要用户自己输入。

框架截面修改不能转入。

框架偏移或者插入点不能被转入。

铰以外的其他连接，譬如隔振器或阻尼器不能被转入
The following Perform3D Inelastic properties are generated for the corresponding Compound Components:
FEMA Beam, Steel Type
FEMA Beam, Concrete Type
FEMA Column, Steel Type
FEMA Column, Concrete Type
以下Perform3D非弹性材料可以生成并形成对应的复合构件。

FEMA Beam, Steel Type
FEMA Beam, Concrete Type
FEMA Column, Steel Type
FEMA Column, Concrete Type
The following Frame Member Compound Components are created during the transfer: 以下Frame Member Compound Components 在转换时将会生成
CpdBmS/CpdColS/CpdBmC/CpdColC/CpdFemaBmS/CpdFemaColS/CpdFemaBmC/CpdFemaColC/ CpdEmbed
Model sections transferred are available as Perform3D Cross Sections.
模型截面可以转换成Perform3D中的横截面。

Rectangular sections for concrete and I-sections for steel retain their shapes - all other sections are displayed with 'No specific shape' when imported.
混凝土矩形截面或钢的I形截面依然保持其所有形状，其他截面在转换后将会显示“无指定形状”。

The following Perform3D sections are created:
以下Perform3D截面将会生成。

Beam, Reinforced Concrete Section梁配筋混凝土截面
Beam, Steel Type, Nonstandard Section梁，钢，非标准截面
Column, Reinforced Concrete Section柱，钢筋混凝土截面
Column, Steel Type, Nonstandard Section柱，钢，非标准截面
Shear Wall, Inelastic Section 剪力墙，非弹性截面
Shear Wall, Elastic Section 剪力墙，弹性截面
General Wall, Inelastic Section普通墙，非弹性截面
General Wall, Elastic Section普通墙，弹性截面
Slab or Shell, Elastic Section板或壳，弹性截面
5. Shells are transferred to Perform3D's Compound Components.
Nonlinear layered shells must be comprised of at least one membrane/shell layer of concrete and one layer of rebar.
壳被转换成Perform3D的混合构件。

非线性层壳必须折算成一种混凝土和一层钢筋的膜或壳层
The layers in the layered shell should be setup as follows and are transferred to the indicated
Perform3D Compound Component.
多层壳必须按以下定义并转换成指定的Perform3D Compound Component。

Conc: 1)MatAng=0, S22 nonlinear->Perform fiber wall. (Axial-Moment behavior)
MatAng=90, S11 nonlinear->Perform fiber wall. (Axial-Moment behavior)
2)MatAng=0 S11 nonlinear->Perform General Wall (Axial-Moment behavior in horizontal)
MatAng=90 S22 nonlinear->Perform General Wall (Axial-Moment behavior in horizontal)
3)MatAng=0 or 90, S11 and S22 nonlinear->Perform General Wall (Axial-Moment behavior in H and V)
混凝土:1)材料角=0，S22非线性----纤维墙（轴向受弯变形）
2）材料角=90，S11非线性----纤维墙（轴向受弯变形）
材料角=90，S22非线性----普通墙（水平轴向受弯变形）
3）材料角=0或90，S11或S22非线性----普通墙（水平或竖向轴向受弯变形）The reinforcement ratio is taken as the sum of all rebar membrane/shell layer thicknesses.
The concrete thickness is taken as the sum of all concrete membrane/shell layer thicknesses.
配筋率是按钢筋膜或壳的总厚度来计算的。

混凝土厚度是按照所有混凝土膜或壳的层厚度计算的。

Only 3- and 4-noded shells are transferred. 3-noded shells are divided into three 4-noded areas. 4-noded shells are sorted by their normal vector, checking for wall/slab/ramp orientation, etc. Mapping is done as follows:
Elastic thin shell -> Elastic/Inelastic Shear Wall in Perform3D
Wall -> Wall in Perform3D
Floor/Ramp -> Slab/Shell in Perform3D
只有3点或4点壳能转。

3节点的壳元被分成3个4节点的壳元。

4节点的壳按照向量分类，检查所有墙板的坐标方向。

按以下操作：
Elastic thin shell -> Elastic/Inelastic Shear Wall in Perform3D
Wall -> Wall in Perform3D
Floor/Ramp -> Slab/Shell in Perform3D
6. Supports are transferred, but the local axis angle is not. Springs are not transferred.
支座可以转换，但是带有局部坐标角度的不能。

弹簧不能转换。

7. Rigid diaphgram constraints are transferred, but only those with a normal in the Z-direction.
刚性楼板约束能转换，但是只有一半沿Z方向的。

8. Masses and the Mass Source are transferred. Only Gravity/Z/Projected-Z mass in global coordinates is transferred.
Only Dead/Live load patterns from the Mass Source loads are transferred.
Loads on beams are converted into point masses using simply-supported beam equilibrium. Mass in Perform3D is specified as lumped mass concentrated at the nodes.
质量和质量源能转化。

但只有重力或z方向的质量能转换。

只有质量源的恒荷载或活荷载能转换。

荷载梁上荷载能转换成节点质量，保证简支梁的平衡。

在Perform3D中可以将质量定义成集中于节点的单质量。

9. Compound Components generated from model objects are automatically assigned to element
groups in Perform3D, and include the orientation of the local axes.
模型生成的构件会自动在Perform3D中形成单元集，包括局部坐标方向。

10. Nodal/Frame Distributed/Frame Point/Area Distributed and self-weight loads are transferred. Area distributed loads are transferred as equivalent point loads at the nodes.
Only Dead and Live load patterns are considered.
集中/框架分布/框架点/面分布以及自重荷载能转换。

面分布荷载可以转换成等效节点荷载。

只有恒荷载或活荷载在考虑范围内。

11. Drift is defined using the highest and lowest nodes that lie along a nearly vertical line.
用在一条竖直线上的最高或最低的节点来定义Drifts（偏移）
12. When importing a model, a default Structure Section is generated in Perform3D. This is a section cut at the base defined by cutting through all
Frames and Areas with supports. Frames are cut at the bottom supported node, and areas are cut using the two bottom supported notes. Slabs are not considered for Perform3D Structure Sections.
当你导入模型，默认的结构截面将会在Perform3D中生成。

这个断面在形成整体断面时生成的。

带有支座的框架或面。

框架按照底部的支座节点剖开，面按照两个底部支撑节点剖开。

在Perform3D Structure Sections中不考虑板的截面。

Note: If supports are not all at one elevation or restraints are assigned at other positions, the Structure Sections should be reviewed.
注意：节点不是全部在一个平面上或者约束不在一个位置，那么结构剖面应该检查。

13. Nonlinear static load cases are transferred to Gravity or Static Pushover Load Cases.
Force-controlled cases are transferred to Linear-Gravity Load Cases, and
Displacement-controlled cases are transferred to Pushover Load Cases.
Scale factors, patterns, etc. need to be input by the user.
非线性静定荷载工况可以转换成重力或静力Pushover 分析工况。

力控制工况可以转换成线性重力工况，位移控制工程可以转换成Pushover工况，需要用户自己定义比例因子，类型等等参数。

14. Nonlinear time history load cases are transferred to Dynamic Earthquake Load Cases.
Time history functions From File are saved in Perform3D's Records directory.
Note: The Perform3D records can be found in the Records folder within the Perform3D installation directory.
非线性时程工况能转换成Dynamic Earthquake工况。

时程函数将保存在Perform3D的Records目录下。

注意：Perform3D的Records文档可以在安装目录下找到。

15. The Analysis Series in Perform3D must be created by the user.
用户必须自己创建一个分析的Series
16. The Perform3D Structure should be reviewed completely before running the model.
在运行分析之前，必须重新检查Perform3D的结构模型。
