摘要:
外廊式教学楼是中小学校典型的建筑形式。汶川地震后，外廊式教学楼震害引起大量研究人员重视。2021年5月21日21时48分，云南大理州漾濞县发生6.4级地震，本文作者详细调查了位于漾濞县的4所典型框架结构外廊式教学楼，以震害较为严重的漾濞一中和花椒园小学为例，分析了结构各部位发生破坏的原因。以震害现象为佐证，得出以下结论：由于横墙的约束，楼板沿纵向平动，各轴构件的本构关系可在同一坐标系下进行对比分析，结构破坏取决于构件沿纵向的极限位移。并在此基础上，从新的角度探讨了多层建筑的抗震能力。
Abstract:
Side corridor school building is a typical building style in primary and secondary schools. After Wenchuan earthquake, the earthquake damage of side corridor school buildings has attracted a lot of researchers’ attention. An M6.4 earthquake happened in Yangbi County, Dali Bai Autonomous Prefecture, Yunnan Province at 21:48 on May 21, 2021. The authors in this paper surveyed 4 typical RC frame side corridor school buildings located in Yangbi County. Taking Yangbi No.1 Middle School and Huajiaoyuan Elementary School as examples, the causes of the damage in each component of the structures were analyzed. Based on the earthquake damage, the following conclusions are drawn: Due to the restriction of the transverse wall, the floor moves along the longitudinal direction and the constitutive relations of the members of each axis can be compared and analyzed in the same coordinate system. The failure of the structure depends on the ultimate deformation capacity of the member along the longitudinal direction. On this basis, the seismic capacity of the structures is discussed from a new perspective.
