【摘要】 围护墙多功能减震结构体系是一种新的减震结构,其中围护墙与主体结构在小震作用下二者共同工作抵抗地震作用,而在中、大震作用下形成TMD减震结构。本文旨在提出该结构体系在小震作用下框架与围护墙协调工作的一种计算方法,为在中大震作用下的后续研究及其在实际工程中的应用提供了理论基础。根据围护墙多功能减震结构中填充墙与外框架的构造特点,提出横向载荷作用下的计算模型;通过变形协调原理对其进行受力分析,建立了单跨单层该多功能墙体结构横向位移及各组成构件受力表达式。计算分析表明:各组件剪力分配只与各组件的刚度及宽度比有关;各组件的受力在λ增大时,填充墙对柱的反作用力逐渐降低,框架梁的反作用力逐渐增大;当λ≤0.02604时,填充墙是主要的受力部件。更多还原

【Abstract】 Enclosure wall multi-functional structure system is a kind of new vibration reducing structure.Under the small earthquake, enclosure wall and the main structure work together to resist seismic action, and under medium and strong earthquakes the TMD damping structure will be formed. It is put forward to a calculation method for the coordination work of framework structure and enclosure wall under small earthquakes. This method provided theoretical basis for the future researches and the application for the structure system. The calculation model under lateral loading is proposed based on the construction features of infill wall and shell frame in the enclosure wall multifunctional vibration absorption structure.The stress expressions of lateral displacement and every component of single span and single layer structure were built with the principle of deformation harmony analysis. The calculation analysis shows that shear force distribution of components is only related to with stiffness and width of components. The reacting forces to the columns gradually decrease while the ones to the framed girder gradually increase as λ increases.更多还原
