SUPER-FEM FOR ANALYSIS OF INELASTIC RESPONSE OF TALL STEEL BUILDINGS SUBJECTED TO EARTHQUAKES

摘要

To provide a practical method for structural engineers to conduct inelastic analysis for seismic-resistant design of tall steel frames, a Super-FEM model is proposed in this paper. The advantage of this model is that the structural degrees of freedom can be reduced. Comparisons are made through a number of examples between Super-FEM and normal FEM. It is shown that satisfactory results with appropriate accuracy can be achieved by Super-FEM.
