填充墙对框架结构约束效应分析

Study on Local Restraint Effect of Filled Walls on Frame Structures

填充墙与框架的相互作用机制非常复杂,为了分析填充墙对框架的约束效应及短柱的形成机制,采用有限元软件ABAQUS建立10个带有填充墙的框架模型,分析开洞率及填充墙刚度不同时,填充墙对框架的约束效应。模型分析结果表明,随着洞率γ减小、填充墙刚度增大,填充墙对柱的约束效应变得明显。研究结果可为结构中填充墙的设计与布置提供参考依据。

The interaction of filled walls and frame structures is very complex. In order to find out the local restraint ef- fect of filled walls on frame structures and the formation mechanism of short columns, the finite element software ABAQUS is used for constructing 10 different frame structure models with filled walls so as to analyze the local restraint effect of filled walls on frame structures under different ratio of aperture and stiffness. The analysis results show that the local re- straint effect of filled walls on frame structures would become more obvious with the reduction of aperture＇ s ratio and the addition of filled walls＇ stiffness, which could provide references for the design and layout of the filled walls in struc- tures.
