Nodal Body Force

Convert Nodal Mass, Load to Mass and Structure Mass assigned to a selected node to a nodal (body) force in a specific direction.  The scale factor (Mass??actor) can be applied in each direction.  This is useful to apply load according to the mass distribution to each node in the pushover analysis.

From the Main Menu select Load > Nodal Body Force

Select Static Loads > Nodal Body Force in the Menu tab of the Tree Menu.

 Load Case Name

Assign the load case name. Click to the right to enter additional load cases and modify or delete existing load cases.

 

Nodes for Nodal Body Force

Use Structural Group: Select the nodes for nodal body force from the existing structural group.  Click to the right to add or modify a structure group.

Node List: Enter the node numbers directly or select the nodes from the screen.

 

Masses to be Converted

Select the type of masses to be converted.

Nodal Mass

Load to Mass

Structural Mass

 

Nodal Body Force Factor

X : Force Factor in X-direction

Y : Force Factor in Y-direction

Z : Force Factor in Z-direction

Note

For a single Load Case, multiple Nodal Body Force Factors can be input. Body Force entered in each node can be checked from the Model View or in the Nodal Body Force Table.
