【摘要】 具有自复位及摇摆特性的结构体系是近些年来提出的新型结构体系,相对于传统的框架和剪力墙结构,这类结构在地震作用下结构的变形和损伤控制等方面具有独特的优势。利用通用有限元软件ABAQUS分别对具有相同框架部分和墙体布置的框架-剪力墙结构、框架-自复位墙结构和纯框架结构的有限元算例进行了静力弹塑性分析和弹塑性时程分析,通过对这三种结构体系的承载力、变形和结构耗能进行对比,来进一步说明框架-自复位墙结构的结构特点,最后通过弹塑性时程分析,对阻尼器对于框架-自复位墙结构抗震性能的作用进行了初步的探讨。更多还原

【Abstract】 Self-centering and rocking structures have been proposed as new structural systems in recent years.Compared with the traditional frame and shear wall structure,this kind of structure has an unique advantages in structural deformantion and damage control under earthquake inputs.In this paper,a frame shear wall structure,a frame self-centering wall structure and a frame structure with the same frame system and walls layout were simulated by using the finite element programe ABAQUS.Both pushover and elasto-plastic time-history analyses were carried out.Carrying capacity,deformation and energy dissipation were compared to further illustrate the structural characteristics of the frame self-centering wall structure.In the end,a preliminary analysis was conducted to study the impact of damper on the frame self-centering wall structure.更多还原
