TAP-86: A three-dimensional frame analysis program for tall buildings

Abstract

TAP-86 Program has three unique features: (1) the use of thin-wall element with opening for analyzing the torsion and warping effect of shear walls under lateral loads; (2) the use of three-dimensional analysis method for calculating the deformation and member forces of tall building structures under lateral and vertical loads; (3) the use of three kinds of dynamic analysis of structures, the plane vibration method for symmetric structures, the one direction seismic wave input method and the two direction seismic waves simultaneously input method for unsymmetric structures where the torsion-couple vibration effect should be taken into account. TAP-86 Program can be used to analyze such tall building systems as space frames, shear walls and tubular structures under static and seismic loads, and to calculate the member forces and reinforcements of beams, columns and shear walls. The program is written in FORTRAN 77 and runs on IBM-4341 and IBM-3031 computers.
