影响偏心结构地震反应的因素综述

偏心结构的地震反应受多种因素的影响,不少研究者对各种影响因素进行了详细分析,并得出了一些有价值的结论。但是由于影响因素多,尤其是当结构进入非弹性反应阶段表现更为明显,并且各因素间还存在明显的相互影响,因此,这方面的研究还存在相当大的难度,当前对各种影响因素的研究并没有形成较为一致的结论。本文分别从结构影响参数和地震动输入等方面对偏心结构地震反应的研究现状进行简要评述,指出当前该研究领域中存在的若干问题和相关看法,以便为更深入地开展偏心结构地震反应分析做必要的准备。

Review of Factors Influencing Earthquake Response of Eccentric Structure

Despite the detailed analysis and the valuable results obtained, the researches of the eccentric structural earthquake response influenced by many factors have not yet arrived at a consistent conclusion because of the coupling of these numerous factors, especially when the structure is in the inelastic response phase. Hence there are many difficulties to be faced in this field. In this paper the results of the influencing parameters and earthquake input are reviewed. Some issues are addressed and some opinions are put forward in this regard for further researches.
