Abstract

While stochastic methods to evaluate wind-induced response of elastic structures are well established, authors have previously proposed stochastic methods to predict wind-induced inelastic response. However, these stochastic methods for elastic and inelastic structures are based on a stationary random process with a fixed mean wind speed and do not consider the rapid variation of mean wind speed as shown in which a typhoon passes through a site. In this paper, inelastic response under wind loads with variation of mean wind speed is predicted by applying methods previously proposed in Ref. [1] and [2]. It is confirmed that proposed methods are also valid for wind loads with variation of mean wind speed by comparison with results of time history response analysis.
