基于结构物的地震观测资料,为估计现有结构的地震反应和损伤状况,将滞后结构的随机估计问题,用伊藤随机微分方程来表述。

• In order to evaluate the seismic response and damage states of existing structures based on seismological observational date of structures, stochastic estimation problems of hysteretic structures are formulated in the form of the Ito stochastic differential equations.
