摘要
本文从能量的观点出发提出了钢筋混凝土框架--剪力墙结构非线性地震反应,在计算中采用了五分段刚度的杆单元模型和考虑各垂直杆剪切刚度的多垂直杆单元模型,并考虑了杆件的轴力--弯矩的相互作用及P-△效应的影响。算例分析表明,结构的能量反应分布与阻尼模型的选取密切相关,结构的地震反应及破损过程与结构能量的吸收、耗散过程存在着密切的关系。
On the basis of energy theory, nonlinear seismic response analysis of reinforced concrete frame-shear wall structure is developed. The bar element model with stiffness in fire different regions and parallel multi-component bar element model considering shear stiffness are used in the calculation. Furthermore, the interaction between the axial force and moment of the bar as well as the influence of P-Δeffect are considered. The results of analysis show that the distribution of structural energy response is closely related to the selection of the damping models. There also exists a close relation between the seismic response, the damage process and the absorbing and dissipating process of the structural energy.
