平面不规则结构设计分析与优化设计研究

Research on Design analysis and Optimization Design of Plane Irregular Structure

通过研究一系列抗震平面不规则结构,得出研究成果:结构的平面布置对结构抗扭刚度影响较大,应强化结构抗扭刚度、弱化结构平动刚度。对平面不规则结构,可通过优化结构平面布局,加强薄弱部位的地震构造措施,加强结构的整体连接,从而增加结构的延性和变形能力,利于加强结构的抗震性能,确保结构抗震安全。就建筑平面不规则结构进行相关的稳定性与抗震性能分析,提出合理的设计模型,并在此模型的基础之上进行优化设计。

Through the study of a series of seismic plane irregular structures, the results obtained are as follows ： the plane arrangement of structures has a great influence on the torsional rigidity of structures ; the torsional rigidity of structures and the translational stiffness of weakened structures should be strengthened. The irregular plane structure, by optimizing the structure layout, strengthen the seismic structural measures of the weak parts of the structure, strengthen the overall connection, thereby increasing the structure ductility and deformation capacity, enhance the seismic performance of the structure, ensure the aseismic safety of the structure.In this paper, the stability and seismic performance of irregular structure of building plane are analyzed. A reasonable design model is put forward, and the optimization design is carried out on the basis of this model.
