摘要
本文运用结构动力分析与钢筋混凝土结构非线性有限元理论,采用等效杆系模型对强震作用下的钢筋混凝土框架-剪力墙结构进行非线性时程分析。考虑了杆件的弯矩-轴力相互作用,钢筋粘结滑移的影响以及P-△效应。算例表明,本文方法及其程序计算时间及占用内存少。同时亦能很好地解释震害和预测地震时结构可能发生的破坏。
A method for analyzing the nonlinear seismic responses of R/C plane frame-wall structures subjected to strong earthquake motions is presented in this paper.The structure is idealized as an assemblage of prismatic members with two rigid zones at its ends.The effects of the interaction between axial force and bending moment in a member,slippage rotation at the ends of members due to the imperfect bond of reinforcing bars and the effects of P-A actions are all considered
in this method.The numerical results show that the presented method and the programmed code are very effective both in computing CPU time and storage reguirement,
and very satisfactory in explaining the earthquake hazards of building structures and predicting the possible damages of newly designed structures.
