钢筋混凝土框架-剪力墙结构非线性地震反应分析
|
摘要
本文从分析的观点研究了钢筋混凝土框架-剪力墙结构非弹性地震反应.在计算中采用等效杆系力学模型,考虑了杆件的轴力-弯矩相互作用、钢筋粘结滑移和P-△效应的影响.算例表明,本文方法及其程序计算时间与占用内存少.采用本文提出的技术,使得高层建筑结构的非线性地震反应分析能在微机上进行,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.
The inelastic response of reinforced concrete plane frame-wall structures subjected to strong ground motions is studied from an analytical standpoint. In the analysis, the structure is idealized as the assemblage of prismatic members with two rigid zones at its ends. The influence of mombers' moment-axial force interaction effects, slippage rotation at the ends of these members due to non-perfective bond of renforcing bars and geometric nonlinearities (often known as "p-Delta" effects) are considered in this method. The numerical results show that the presented method and programed code are very effective in computing CPU time and storage. With the technique proposed, analysis of nonlinear seismic response of large tall building structures can be carried out in a micro-computer,and it is very satisfactory in explaining earthquake hazerds of building structures and predicting the possible damages.
