Energy-based numerical evaluation for seismic performance of a high-rise steel building
H.D. Zhang and Y.F. Wang
Abstract
As an alternative to current conventional force-based assessment methods, the energy-based seismic performance of a code-designed 20-storey high-rise steel building is evaluated in this paper. Using 3D nonlinear dynamic time-history method with consideration of additional material damping effect, the influences of different restoring force models and P-
