Robot结构分析风雪荷载对话框【翻译】
Snow/Wind Loads
Snow/wind loads can be generated by
?Clicking the Loads menu > Wind & Snow > Wind and Snow 2D/3D.
?Clicking .
Note: The Snow/Window Loads option is available only for plane frame and plane truss structures. You can generate snow/wind loads for 3D frames and 3D trusses. This option is unavailable if you have not defined a structure.
注意：“雪/窗荷载”选项仅适用于平面框架和平面桁架结构。可以为三维框架和三维桁架生成雪/风荷载。如果尚未定义结构，则此选项不可用。
The Snow/Wind Load dialog has conditions for which snow/wind loads are generated:
“雪/风荷载”对话框具有生成雪/风荷载的条件：
?Envelope - Defines those structure elements for which snow and wind loads will be generated. The numbers of the selected nodes create the envelope. It is a required parameter for defining global snow and wind coefficients of a structure.
??包络线-定义将产生雪荷载和风荷载的结构构件。选定节点的编号将创建封套。它是定义结构整体雪和风系数的必需参数。
Note: To correctly generate snow and wind loads this option must be specified.
注意：要正确生成雪和风荷载，必须指定此选项。
To select an envelope:
要选择信封：
1. Enter the numbers for consecutive nodes.输入连续节点的编号。
2. Highlight the nodes in the drawing area.高亮显示绘图区域中的节点。
3. When defining the envelope manually, you can create either an open or closed envelope (depending on whether you go back to the first node.)手动定义封套时，可以创建打开的或关闭的封套（取决于是否返回到第一个节点）
?Auto - Begins generating the automatic envelope. Parameters are set according to the selected options for automatic envelope recognition.自动-开始生成自动包络线。参数根据选定的自动信封识别选项进行设置。?Without Parapets - When selected, an envelope is generated automatically without regard to parapets.?无女儿墙-选中时，将自动生成不考虑女儿墙的封套。
?Without Cavities - When selected, an envelope is generated automatically without regard to cavities. Fictitious envelope elements are created instead.无空腔-选择该选项后，将
自动生成不考虑空腔的包络线。而是创建虚构的信封元素。
?With Base Not on the Ground - When selected, an envelope is generated automatically without regard to a base on the ground; therefore, letting you create an envelope for aerodynamically insulated structures.当基础不在地面上时-选中时，将自动生成包络，而不考虑地面上的基础；因此，可以为空气动力学绝缘结构创建包络。?Isolated roofs - If this option is selected, the structure is an isolated roof and loads are generated only on the isolated roof.独立屋顶-
如果选择此选项，则结构为独立屋顶，荷载仅在隔离屋顶上生成。
To define snow/wind loads, you must specify basic parameters for the structure:要定义雪/风荷载，必须指定结构的基本参数：
?Total depth - Defines the building depth (length). It is a required parameter for defining global snow and wind coefficients of a structure.总深度-定义建筑深度（长度）。它是定义结构整体雪和风系数的必需参数。
Note: To correctly generate snow and wind loads this option must be specified.注意：要正确生成雪和风荷载，必须指定此选项。
?Bay spacing - Defines the bearing element spacing on a structure length. It is a required parameter that accounts for the accumulation of loads from the appropriate side walls.间隔间距-定义结构长度上的承重构件间距。这是一个必需的参数，用于说明来自适当侧壁的荷载累积。
Note: To correctly generate snow and wind loads this option must be specified.注意：要正确生成雪和风荷载，必须指定此选项。
At the bottom of the dialog, there are the following 2 options:在对话框的底部，有以下两个选项：
?Wind - When selected, creates wind load cases during the generation of snow/wind loads; when cleared, prevents Robot from creating wind load cases.风-选中时，在生成雪/风荷载期间创建风荷载工况；清除后，防止机器人创建风荷载工况。
?Snow - When selected, creates snow load cases during the generation of snow/wind loads; when cleared, prevents Robot from creating snow load cases.雪-选中时，在生成雪/风荷载期间创建雪荷载工况；清除后，阻止机器人创建雪荷载工况。
At the bottom of the dialog is the Display note after load generation option. When
selected, Robot runs the text editor that displays the load values it calculated for individual snow and wind load cases. When cleared, Robot saves the files containing the calculation notes for the snow and wind loads cases to the local user folder
\Users\...\Documents\Autodesk\Output.该对话框的底部是“加载后显示注释生成”选项。选中后，Robot将运行文本编辑器，该编辑器将显示它为单个雪和风荷载情况计算的荷载值。清除此选项后，Robot会将包含雪荷载和风荷载计算注释的文件保存到本地用户文件夹\Users\…
\Documents\Autodesk\Output。
Clicking Parameters opens the dialog for setting detailed parameters for snow and wind loads.单击“参数”将打开一个对话框，用于设置雪和风荷载的详细参数。
Note: This button is inactive until an envelope, building spacing, and depth are specified.注意：在指定封套、建筑间距和深度之前，此按钮处于非活动状态。
