Methods of creating the model创建模型的方法

There are three methods of creating the structure data:

有三种创建结构数据的方法：

1.

Using the STAAD.Pro Physical Modeler interface,

使用专业技术人员物理建模器接口, 2.

Using the traditional STAAD.Pro analytical modeling interface,

使用传统专业技术人员分析建模界面， 3.

Using the command file

使用命令文件

The physical model is used to draw structural elements as they are physically constructed. The program will then decompose this into an analytical modeling which is passed to the STAAD.Pro analysis and design engine when you run your model.

物理模型用于绘制实际构造的结构元素。然后，程序将把它分解成一个分析模型，然后传递给专业技术人员运行模型时的分析和设计引擎。

The analytical model is a finite element model of the structure which is typically processed directly by the analysis and design engine.

模型的分析通常是由有限元直接进行的。

The command input file is a text file which contains the data for your structural model. This file consists of simple English language-like commands. This file is created for you behind the scenes for you when you model your structure using either the physical modeler interface or the analytical model interface.

Methods of creating the model创建模型的方法

命令输入文件是一个文本文件，其中包含结构模型的数据。这个文件由简单的英语语言命令组成。当您使用physical modeler界面或分析模型界面对结构建模时，会在幕后为您创建此文件。

The physical model will be linked to the command input file so any changes to your physical model must be made using the physical modeler interface. This ensures data integrity when the program decomposes the physical model. You can \directly, either using the STAAD.Pro analytical modeling interface or using the command input file editor.

物理模型将链接到命令输入文件，因此必须使用physical modeler界面对物理模型进行任何更改。这确保了程序分解物理模型时的数据完整性。您可以使用专业技术人员分析建模界面或使用命令输入文件编辑器。

You can switch back and forth between the analytical modeling interface and the command input file editor for models created by either of those methods.

对于通过这些方法之一创建的模型，可以在分析建模界面和命令输入文件编辑器之间来回切换。

All three methods are described in this tutorial, with a detailed focus on the STAAD.Pro Physical Modeler interface.

这三种方法都在本教程中进行了描述，并详细介绍了专业技术人员物理建模器接口。

T.1 Description of the tutorial problem

The structure for this project is a single bay, single story steel portal frame that will be analyzed and designed.

本工程结构为单开间单层门式刚架，将进行分析和设计。

一、Portal Frame model

An input file called C:\\Users\\Public\\Documents\\STAAD.Pro CONNECT Edition\\Samples\\ US\\Tut-01-portal.std containing the input data for this structure is installed with the program. This file contains what would otherwise have resulted had we followed the procedure explained in T.1 Creating the model using the command file .

一个名为C:\\Users\\Public\\Documents的输入文件\\专业技术人员CONNECT

Edition\\Samples\\US\\Tut-01-门户网站.std包含此结构的输入数据的程序随程序一起安装。这个文件包含了如果我们按照T.1中解释的使用命令文件创建模型的过程，就会产生的结果。
