Loads, Load Cases, and Load Combinations

Gravity "Loads" are defined in RAM Modeler. These can be in the form of surface loads, line loads, and point loads. Additional lateral loads can be defined for load cases in RAM Modeler nodal loads and pressure loads.

"Load Cases" are defined as story forces in Analysis - Load Cases Mode of RAM Frame or as nodal and pressure loads in RAM Modeler. These can be in the form of wind loads, seismic loads, dynamic loads, or other user-defined loads. Before an analysis is performed, the load cases that will be analyzed are chosen. Reports are then available for the load cases that have been analyzed. Load cases from the Analysis - Load Cases mode are utilized in Shear Wall Forces - Load Cases mode.

"Load Combinations" are defined in each mode independently in Analysis-Load Combination, Steel Standard and Steel Seismic Modes. Load combinations describe the way load cases act on the structure simultaneously. Only load cases that have been analyzed in Analysis Mode are available to be included in load combinations. Load combinations from the Analysis - Load Combinations mode are utilized in Shear Wall Forces - Load Combinations mode.
