RC框架填充墙抗震性能提升方法综述

REVIEWS ON SEISMIC BEHAVIOR IMPROVEMENT APPROACHES ON INFILLS OF RC FRAMES

填充墙在地震作用下平面内外均发生严重的破坏,同时,填充墙与周边框架的相互作用使结构发生非延性破坏形态,不符合延性设计理念。文中分析了实际震害中填充墙的破坏形态,利用已有文献,归纳了改善填充墙抗震性能的方法,分析了各种方法的特点,着重对摇摆砌体填充墙进行阐述,并进行了展望。

Earthquake investigation demonstrates that infill walls suffer severe damage both in-plane and out-of-plane.Additionally,interaction between infill walls and surrounding frames results in non-ductile failure modes,which deviate from the concept of ductile design.This paper analyzes the failure modes of infill walls in earthquakes,in which approaches on the methods to enhance seismic performance of infills based on existing literature are summarized.Characteristics of various methods are analyzed,and rocking masonry infill walls are specifically discussed.Finally,future prospects of improvement of infills are proposed.
