本文主要是介绍【SAP2000】在框架结构中应用分布式面板荷载Applying Distributed Panel Loads to Frame Structures，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在框架结构中应用分布式面板荷载

Applying `Distributed Panel Loads` to `Frame Structures`

使用"Uniform to Frame"选项,可以简单地将荷载用于更多样化的情况。
With the “Uniform to Frame” option, loads can be easily used for a greater diversity of situations.

用户只需定义要施加在每个面对象上的均布荷载值。SAP2000程序计算并乘以所包含的框架和/或节点的影响宽度和/或面积。用户可以完全控制荷载的分布方式,可以根据每个面对象的局部轴1或局部轴1和2进行单向或双向分布。
The user only needs to define the values of the uniformly distributed loads to be applied to each area object. The SAP2000 program calculates and multiplies by the influence widths and/or areas of the included frames and/or nodes. The user has full control over the distribution of the loads, which can be one-way or two-way, according to local axis 1 or local axes 1 and 2 of each area object.

使用"None"面对象和不同的划分选项,用户可以选择避免建模覆层和其他次要结构,但在生成的荷载离散化方式中考虑它们。
By using "None" area objects and different division options, the user can choose to avoid modeling coverings and other secondary structures, but consider them in the way the generated loads are discretized.

面板荷载的分配

Attribution of Loads on Panels

首先,需要选择None面对象,并通过选项Assign -> Area Loads -> Uniform to Frame(Shell)分配相应的荷载。荷载分布可以是单向或双向的,加载方向可以根据面对象的整体轴或局部轴。
First, it is necessary to select the None area objects and assign the respective loads through the option Assign -> Area Loads -> Uniform to Frame (Shell). The load distribution can be one-way or two-way, and the loading direction can be according to the global or local axes of the area objects.

显示结果荷载的选项

Options for Displaying Resulting Loads

要显示框架对象上的结果荷载,只需选择选项Display -> Show Load Assigns -> Area -> Uniform Load to Frames Resultants。
To display the resulting loads on the frame objects, simply select the option Display -> Show Load Assigns -> Area -> Uniform Load to Frames Resultants.
