摘要: 为充分了解抗震结构填充墙的开裂机理和抗裂能力,并为砌块填充墙的抗震性能提供依据,文中采用有限元方法对砌块墙体的面内开裂进行了分析.研究发现,抗震结构中填充墙的开裂机理十分复杂,但其开裂行为及抗裂能力主要决定于墙体所处的层间位移角以及自身的材料强度.文中还得到了不同弹性模量的砌块墙体在不同裂缝限值下的层间位移角值,可应用于填充墙框架结构基于性能的抗震设计中.

Abstract:

In order to reveal the cracking mechanism and the anti-crack performance of infill walls of aseismic structures,and provide information for the performance-based seismic design of infilled structures,the in-plan cracking of masonry infill walls is analyzed by means of finite element method. The results show that the cracking mechanism of the infill walls is very complicated,and that the cracking and anti-crack performance mainly depends on the storey drift angle of the frame and the strength of wall materials. The story drift angles of the masonry infill walls with different elastic moduli are obtained in different cracking widths. The result can be applied to the performance-based seismic design of infilled frame structures.
