A procedure and a computer program are developed for the linear structural analysis of frame and shear wall buildings subjected to both static and earthquake loadings. The building is idealized by a system of independent frame and shear wall elements interconnected by floor diaphragms which are rigid in their own plane. Within each column, bending, axial and shearing deformations are included. Beams and girders may be nonprismatic and bending and shearing deformations are included. Also, shear panels can be considered. Finite column and beam widths are included in the formulation. Nonsymmetric, nonrectangular buildings which have frames and shear walls located arbitrarily in plan can be considered. Three independent vertical and two lateral static loading conditions are possible. The static loads may be combined with a lateral earthquake input which is specified as an acceleration spectrum response. Three-dimensional mode shapes and frequencies are evaluated. Frame and shear walls are considered as substructures in the basic formulation; therefore, for many structures, input data preparation can be minimized and a significant reduction in computational effort can result in this approach.
