Abstract

This study addresses the analysis of stochastic crosswind response of tall buildings with bilinear hysteretic restoring force character. The building response is represented in fundamental modal response. Both wind speed regions with and without nonlinear aerodynamic damping effect are considered. The equivalent nonlinear equation (ENEL) approach is used for estimating response statistics, which include root-mean-square value, kurtosis, probability density distribution, extreme value distribution and fatigue damage. Response history analysis is also performed to demonstrate the accuracy of this analytical framework. The inelastic crosswind response characteristics are discussed though a parametric study to explore the potential benefit of inelastic building design.
