【摘要】 全框支剪力墙结构是指上部剪力墙全部未落地而由底部框架结构转换的结构体系。近年来轨道交通车辆段上盖大量开发,为满足功能要求,全框支剪力墙结构在轨道交通物业开发中有较多的现实需求。本文采取理论分析与数值模拟的方法,结合一实际全框支剪力墙结构工程,分析了现有的侧向刚度比控制方法在全框支剪力墙结构体系中的适用性。结果表明:现有的结构侧向刚度计算方法不完全适用于全框支剪力墙结构。现行规范中的结构侧向刚度计算方法无法有效控制全框支剪力墙结构中转换层的刚度,因此有必要讨论并提出该结构体系合理的刚度比控制指标。同时,以现行侧向刚度比控制方法为原则设计时,可能导致结构底部框架构件截面过大,致使结构经济性和安全性较差。更多还原

【Abstract】 Fully frame supported shear wall structure refers to the structural system in which the upper shear wall is not all landed and the bottom frame structure is transformed.In recent years,the upper cover of rail transit car depot has been developed a lot.In order to meet the functional requirements,fully frame supported shear wall structure has more realistic demands in the development of rail transit property.In this paper,the applicability of the existing lateral stiffness ratio control method in the frame-supported shear wall structure system is analyzed by theoretical analysis and numerical simulation combined with a real full frame supported shear wall structure project.The results show that the existing lateral stiffness calculation method is not fully applicable to the full-frame supported shear wall structure.The current calculation method for lateral stiffness of structures in the standard cannot effectively control the stiffness of the transfer layer in the full frame supported shear wall structure.Therefore,it is necessary to discuss and propose reasonable stiffness ratio control indicators for this structural system.At the same time,when the current lateral stiffness ratio control method is used as the design principle,it may lead to excessive cross-section of the bottom frame components of the structure,resulting in poor economic and safety performance of the structure.更多还原
