Abstract
An inelastic analysis program for three-dimensional structures subjected to static/gravity loads and (or) dynamic loads in the form of three translational and orthogonal components of base motions is described. Using incremental integration technique, the program computes structural response as a function of time. Deformation history of elements within the structure can be traced and pertinent information obtained via user element subroutines. Each node can possess up to six displacement degrees of freedom and can accommodate user elements with any specified nodes and degrees of freedom per node. The program is very flexible for modelling different structural configurations, and components like beam column elements, shear wall elements, slab elements, semirigid connection elements, and inelastic spring elements can be easily added to the base program. Key words: inelastic analysis, three-dimensional structures, earthquake, computer program, dynamic, stiffness matrix, base accelerations, unbalanced forces, element subroutines.
