【摘要】 自汶川地震后许多学者提出了不少新型的结构形式,砌体结构与混凝土墙组合结构就是其中的一种。在前人的分析与研究基础上,提出一种相对合理的砌体墙与混凝土墙布置方式,将普通砖砌体房屋中间部分砖墙改为混凝土剪力墙形成封闭的筒体,混凝土筒体贯通至房屋顶层,采用大型有限元软件LS-DYNA对这类结构进行了研究,模拟了在地震荷载下组合结构的响应过程,以及组合结构的破坏及倒塌形式。仿真分析结果与前人的实验结果吻合,可以初步得到该形式的组合结构受力特点及破坏机理,进一步验证了同一结构中两种不同材料墙体的协同工作性能、抗震性能和大变形下的破坏特征。更多还原

【Abstract】 After the earthquake of Wenchuan,many scholars put forward a lot of new type of structure,masonry structure and reinforced concrete wall structure is one of them.In previous analysis and research basis,a relatively reasonable kind of masonry wall and reinforced concrete wall arrangement is introduced in the thesis,the ordinary brick masonry building among part of reinforced concrete shear wall brick wall to form a closed the cylinder body,reinforced concrete cylinder breakthrough the top floor,LS-DYNA,software of finite element,is used to study the structure,simulations of the response procedures of composite structure under earthquake load are made,as well as the destruction of the structure and form of collapsed.The simulation result as the same previous experiment,can get this form of combination preliminary structural characteristics and failure mechanism,further verified the structure of two different materials wall cooperative work performance,the seismic performance and large deformation characteristics of failure.更多还原
