Problem Description
Incorrect Building Story Shear and Frame Story Shears are reported when dynamic load cases are analyzed with gravity load cases only. Correct results are obtained when only dynamic load cases are analyzed or when the dynamic loads are analyzed with both gravity and static seismic load cases. The issue affects models with semirigid diaphragms and two-way decks. The defect does not affect the following results: nodal displacements, story displacements, and member forces.
Reason
The program is not processing results for gravity columns and walls correctly.
Solution
The issue will be resolved in the release after v15.03.00. In the meantime, analyze dynamic load cases with gravity load cases and static seismic load cases.
