Abstract: In this paper, some treatment of the SAP84 Finite Element Software on solving complicated tall building with shear wall has been presented. The structure model,substructure function and solving procedure of SAP84 software for the dynamic static analysis of the tall building with shear wall has been discussed. The details of computation for analysis of 25 floors complicated tall building with shear wall has been carried out on micro-computer 0520A and we obtained very good result.
