Panel pressure and beam-column analyses are both referred to as superimposed loads. They are "superimposed" in that their results are computed separately and then added directly to the results from the primary input loads.
Panel Pressure Enables panel pressure analysis. Reaction moments and shear loads from pressure are computed at the midspan and the ends of the panel according to the assumed boundary conditions defined in the drop-down menu. These moments and shears are superimposed on the primary loads to find the critical margin of safety. See Panel Pressure.
Beam-Column Moments Enables beam-column analysis. Beam-column moments and shear loads are computed at the midspan and ends of the panel. These moments and shears are superimposed on the primary loads to find the critical margin of safety. See Beam-Column.
Initial Imperfection Defines a midspan imperfection for beam-column analysis. See Beam-Column.
Zero Out FEA Computed Moments (FEA loads only) If this option is enabled, all moments from the FEM will be ignored. Only the membrane loads are imported and zero curvature boundary conditions are assumed. If this option is disabled, all load components from the FEM are imported.
