sap2000 混凝土框架设计步骤

  以下内容由sap2000帮助文件翻译而来。

   The following sequence describes a typical concrete frame design process for a new building. Note that although the sequence of steps taken may vary, the basic process probably will be essentially the same.

   下面一系列步骤描述了一个新建混凝土框架的典型设计过程。虽然采取的设计步骤可能不同，但基本过程本质上是相同的。

1. Use the Design menu > Concrete Frame Design > View/Revise Preferences command to choose the concrete frame design code and to review other concrete frame design preferences and revise them if necessary. Note that default values are provided for all concrete frame design preferences, so it is unnecessary to define any preferences; however, review the preferences, and if necessary change them, to ensure they are acceptable.  

     使用Design menu > Concrete Frame Design > View/Revise Preferences 命令，可用来选择混凝土框架设计规范，检查其他混凝土框架设计参数并可在必要时进行修改。注意，所有的混凝土框架设计参数均有缺省值，因此，没有必要定义任何参数；但是，仍需检查设计参数，若有必要，可进行修改，以确保这些参数是适用的。

   2.Create the building model. See Modeling Process for more information.

    创建建筑模型。参考“建模过程”可得到更多信息。

   3.Run the building analysis using the Analyze menu > Run Analysis command. If desired, animate the deformed shapes and mode shapes in 3-D perspective by clicking the Start Animation button in the status bar at the bottom of the screen. Animate shell structures displaying stress contours with the corresponding deformed shapes in full 3-D perspective. While displaying mode shapes or deformed shapes, the vector being displayed can be instantaneously changed with the '+/-' buttons that will appear at the bottom of the screen. Use the Options menu > Sound command to turn the sound associated with the animation off or on.

   使用Analyze menu > Run Analysis命令进行建筑结构分析。若有需要，可点击屏幕底部的状态栏上的开始动画按钮以3维视角形式动画显示变形后的物体形状和模态。可以以全三维视角动画显示壳结构变形后物体上的应力云图，显示图上的矢量可通过屏幕底部的'+/-'按钮来动态调整。使用 Options menu > Sound 命令可关闭或打开相配套的声音。

  4.Assign concrete frame overwrites, if needed, using the Design menu > Concrete Frame Design > View/Revise Overwrites command. Note that frame objects must be selected before using this command. Also note that default values are provided for all concrete frame design overwrites, so it is unnecessary to define any overwrites; however, use this command to review the values, and if necessary change them. Note that the overwrites can be assigned before or after the analysis has been run.

   指定混凝土框架覆盖值，若有必要，使用Design menu > Concrete Frame Design > View/Revise Overwrites命令。注意，在使用该命令之前，框架物体必须被选择。同时注意，对于所有混凝土框架设计，程序均提供了缺省的覆盖值，因此，没有必要定义任何值。仍需检查设计覆盖值，若有必要，可进行修改。注意，覆盖值可在分析开始之前或分析完成之后指定。

   5.To use any design load combinations other than the defaults created by the program for the concrete frame design, click the Design menu > Concrete Frame Design > Select Design Combo command. Note that design combos must already have been created by clicking the Define menu > Combinations command.

   当需要使用与程序默认生成项不同的设计荷载组合时，点击Design menu > Concrete Frame Design > Select Design Combo 命令，注意，必须在之前通过点击Define menu > Combinations命令建立设计组合值。

   6.Click the Design menu > Concrete Frame Design > Start Design/Check of Structure command to run the concrete frame design.

   点击Design menu > Concrete Frame Design > Start Design/Check of Structure命令运行混凝土框架设计。

   7.Review the concrete frame design results by doing one of the following:

   通过下列方法之一查看混凝土框架设计结果：

• Click the Design menu > Concrete Frame Design > Display Design Info command to display design input and output information on the model.
• 点击Design menu > Concrete Frame Design > Display Design Info命令，可显示设计时的输入参数，也可显示模型上的输出信息。

• Right click on a frame object while the design results are displayed on it to enter the interactive design mode and interactively design the frame object. Note that while in this mode, overwrites can be reviewed and changed with the results of the new design displayed immediately.

• 当设计结果显示于框架物体上时，右键点击框架物体，可进入交互设计模式，可交互进行框架物体设计。注意，在该模式下，可以检查覆盖值，覆盖值随新设计显示的结果而变化。

If design results are not currently displayed (and the design has been run), click the Design menu > Concrete Frame Design > Interactive Concrete Frame Design command and then right click a frame object to enter the interactive design mode for that object.

             如果当前没有显示设计结果（而设计已被运行），点击Design menu > Concrete Frame Design > Interactive Concrete Frame Design命令，右键框架单元，进入该单元的交互设计模式。
