摘要

本文应用改进的光滑滞回模型,采用等效线性化技术推演了一类具有非线性滞回特性的三维连续体结构非平稳随机响应分析的有限元列式,并以该法编制的程序进行算例分析证实了其合理性和可靠性。
A finite element formulation for a class of nonlinear hysteretic threedimensional continua subjected to stochastic nonstationary excitation is developed by means of an equivalent linearization technique and an improved smooth nonlinear restoring force model. An example is presented to show thai the method is reasonable.
