Applied Story Forces

The Process - Results-Applied Story Forces command displays generated story forces for seismic, wind and user-defined lateral load cases (it also displays gravity loads defined on semirigid diaphragms with two-way slabs). The forces corresponding to a chosen load case are displayed with arrows at locations where they are applied. If a level story consists of multiple diaphragms, the forces applied to each diaphragm are displayed.

When the command is invoked, the analyzed load cases are listed and can be selected. Show Magnitude and Show Coordinates options add text next to the arrows to display the magnitude of the forces and their coordinates, respectively. Arrow size can also be scaled by setting arrow scale size. Note that no value less than zero is allowed and the default value is 1.0. In addition, two options for scaling types for arrows are provided: Log and Linear scaling. Select the Display option to display the forces and unselect it to clear the arrows from the screen; note that merely closing this diagram or invoking Reset Model button does not remove the arrows from the screen.
