- A modified version of the ETABS (2) computer program, which can be used for the linear structural analysis of buildings subjected to static loads and dynamic earthquake loads, is documented. Efficient model formulation and problem solution is achieved by idealizing the building as a system of frame and shear wall substructures inter-connected by floor diaphragms which are rigid in their own plane. The extended capabilities of the enhanced program include: the analysis for the gross building response quantities including story deflections, drifts, shears, torques, and over-turning moments; the ability to account for second-order contributions to the over-turning and torsional moments in static and dynamic analysis; a procedure for approximate static and dynamic analysis without the detailed structural member definition; the use of improved modal combination techniques in response spectrum analysis; automatic generation of UBC and ATC equivalent static lateral seismic forces; calculation of individual member stress ratios (code type stress checks); effective mass calculation for model verification; and a data check feature which can be used to verify input prior to full execution.
