MAXIMUM RESPONSE EVALUATION OF BASE ISOLATED BUILDINGS AGAINST PULSE-LIKE GROUND MOTIONS

Abstract

The objectives of this paper are to analyze nonlinear response and establish the method of evaluating the maximum response of base isolated buildings against the pulse-like ground motions. To achieve the objectives, we consider the pulse-like ground motions as the sinusoidal pulse input and propose the prediction method based on the theoretical solutions and energy balance with single-degree-of-freedom system. The proposed method in this paper evaluates approximately the maximum response against the pulse-like ground motions.
