Generated Load Combinations

All generated combinations are normalized so that they can be compared against an interaction equation value of 1.0. For some implementations of ASD the allowable stresses can be increased by 1/3 for wind and seismic loads. This is handled in the program by assigning factors of 0.75 in the load combinations (i.e., the loads are factored down rather than the allowable stresses being factored up). Note that Dynamic and Other type load cases are not included in the automatically generated load combinations; if desired, custom combinations which include these must be created by the user.

Refer to the Load Combination Generator Manual for more information about the generated load combination templates installed with the program.
