【摘要】：结构连续性倒塌由于具有发生时间短、破坏规模大、造成生命财产损失严重等特点，因而日益受到公众的关注和研究者的重视。目前国内外针对框架结构抗连续倒塌的分析研究较多，而对钢筋混凝土框架-剪力墙结构的相关研究相对较少。钢筋混凝土框架-剪力墙结构在我国的城镇建设中较多，其抗连续性倒塌性能对于保证人民的生命安全和减少财产损失有重要意义。因此，本文拟应用SAP2000有限元分析软件，，采用备用荷载路径法对钢筋混凝土框架-剪力墙结构的抗连续性倒塌性能进行分析，主要研究内容如下：（1）采用线性静力分析法及线性动力分析法，拆除底层不同位置柱后，分别对框架结构和框架-剪力墙结构的内力和位移变化规律的影响进行分析。（2）采用非线性静力分析法，拆除底层不同位置柱后，分别对框架结构和框架-剪力墙结构的塑性铰发展规律、极限承载力和延性的影响进行分析。（3）采用线性静力分析、非线性静力分析及线性动力分析方法，拆除底层相同位置柱后，分析比较框架结构与框架-剪力墙结构的内力、变形、极限承载力及延性的异同。（4）采用线性动力分析方法，分析比较拆除所有层柱与仅拆除底层柱后分别对剩余框架结构和剩余框架-剪力墙结构的影响。
[Abstract]:Structural continuous collapse has been paid more and more attention by the public and researchers because of its short time large scale of destruction and serious loss of life and property. At present, there are many researches on continuous collapse resistance of frame structures at home and abroad, but relatively few researches on reinforced concrete frame-shear wall structures. Reinforced concrete frame-shear wall structures are widely used in urban construction in China, and their ability to resist continuous collapse is of great significance to ensure the safety of people's lives and reduce the loss of property. Therefore, in this paper, SAP2000 finite element analysis software is used to analyze the continuous collapse resistance of reinforced concrete frame-shear wall structures by the method of spare load path. The main research contents are as follows: (1) after removing the different positions of the bottom column by linear static analysis and linear dynamic analysis, The influence of internal force and displacement of frame structure and frame-shear wall structure is analyzed respectively. (2) after removing the column at different positions of bottom layer by nonlinear static analysis, The influence of plastic hinge development, ultimate bearing capacity and ductility of frame structure and frame-shear wall structure are analyzed respectively. (3) Linear static analysis, nonlinear static analysis and linear dynamic analysis are used. After removing the column at the same position, the similarities and differences of internal force, deformation, ultimate bearing capacity and ductility between frame structure and frame-shear wall structure are analyzed and compared. (4) Linear dynamic analysis method is used. The effects of removing all floor columns and only the bottom columns on the residual frame structure and the residual frame-shear wall structure are analyzed and compared.
