摘要: A random vibration method is developed for the response analysis of hysteretic structural systems under stochastic two-dimensional earthquake excitations. The biaxial restoring force modelled by coupled non-linear differential equations; statistics are obtained using equivalent linearization technique. validity proposed model appraised available loading tests reinforced concrete columns. parametric study was performed to examine significance effects interaction practical evaluate extreme also presented.
