CreateandApplyStructuralLoads创建和应用结构荷载

1、Robot 中英对照说明书】Create and Apply StructuralLoads创建和应用结构荷载Before you can analyze the structure, you need to create and apply load cases.在分析结构之前，需要创建和应用荷载工况。1. Create Load Cases1创建荷载工况Load cases are the loads that act on the structure.荷载工况是作用在结构上的荷载。For each case:对于每种情况：1. Assign a load case name and nu

2、mber. You can also keep the default values.1 .指定荷载工况名称和编号。也可以保留默认值。2. Select a load case nature: dead, live, wind, snow, temperature, accidental or seismic.2.选择荷载工况性质：静荷载、活荷载、风荷载、雪荷载、温度、意外荷载或地震荷 载。3. Click Define to add the new definition to the list of defined load cases.4. 单击“定义”将新定义添加到已定义荷载工况的列表中

3、。2. Apply Loads2施加荷载You can apply loads from the Load Definition dialog, or directly from the load tables.可以从“荷载定义”对话框或直接从“荷载表”应用荷载。To define the loads acting in a defined case using load tables:要使用载荷表定义作用在已定义情况下的载荷，请执行以下操作：1. In the Loads table, select a load case from the Case column.1 .在“负荷”表中，从“

4、工况”列中选择一个工况。2. Select a load type from the Load type column.2.从“荷载类型”列中选择荷载类型。3. Select the appropriate bars or nodes from the List column.3.从列表列中选择适当的条形图或节点。When you select the applied load type, the load table row is adjusted accordingly. Only the columns that define the load type display.选择应用的荷载类

5、型时，荷载表行将相应调整。仅显示定义荷载类型的列。Topics in this section本节主题? Load Cases?荷载工况A load case is a combination of different types of loads.?荷载工况是不同类型荷载的组合。?荷载定义?

6、类型。? Load Case Combinations?荷载工况组合For each project it is important to verify the Ultimate Limit State (ULS), as well as the Serviceability Limit State (SLS).?对于每个项目，验证极限状态(ULS和正常使用极限状态(SLS)非常重要Load Cases荷载工况A load case is a combination of different types of loads.荷载工况是不同类型荷载的组合ODuring the analysis,

7、loads or forces are applied to the structure, and the resulting deflections are measured. These loads and forces can be combined to create one or several load cases.在分析过程中，对结构施加荷载或力，并测量由此产生的挠度。这些荷载和力可以组合在一起，以创建一个或多个荷载工况。There are several different types of loads that can be applied depending on the

8、situation you want to simulate.根据要模拟的情况，可以应用几种不同类型的载荷。Topics in this section本节主题Create load cases创建荷载工况Follow the instructions below to create a load case.按照以下说明创建荷载工况。Modify load cases修改荷载工况Follow the instructions below to modify a load case that was previously created.按照以下说明修改先前创建的荷载工况。Delete load

9、 cases删除荷载工况Follow the instructions below to delete one or several load cases.按照以下说明删除一个或多个荷载工况。Load Types dialog荷载类型对话框Apply loads to structure elements向结构构件施加荷载Once a load case has been set up, it can be applied to structure elements such as nodes, bars, or surfaces.一旦设置了荷载工况，就可以将其应用于结构图元，例如节点、杆或曲

10、面。Load Types Symbols荷载类型符号If loads are defined on the Loads layout, a legend of the defined load types is displayed in the bottom right corner of the drawing area. The legend contains a load symbol and units used during the load definition. The size of load symbol descriptions depends on the font size settings.如果在“荷载”布局上定义了荷载，则已定义荷载类型的图例将显示在绘图区 域的右下角。图例包含载荷符号和载荷定义期间使用的单位。加载符号说明的大小取决于字体大小设置。Define Additional Loads for Dynamic Calculations为动态计算定义附加荷载Parent topic: Create and Apply Structural Loads
