【摘要】 通过汶川地震震害调查,探讨多层砌体结构窗下墙体的破坏,分析破坏规律、墙体的窗下墙设计,对多层砌体结构窗下墙的破坏模式进行分析。通过分析发现窗下墙在地震作用下同样处于危险状态,窗下墙的破坏模式是一种延性破坏模式,应对砌体窗下墙破坏进行深入研究。更多还原

【Abstract】 Through investigation of Wenchuan earthquake damage,the failure of spandrel walls in multi-story masonry structures is discussed and the rule of breakage is analyzed in this paper.The design method is also proposed in this paper.This paper also analyses the failure mode of spandrel walls.The analytical detection discovers that earthquake can cause spandrel walls under threat.The failure mode of spandrel wall is ductility destruction.it’s necessary to do more research about the failure of spandrel wall.更多还原
