摘要：在这项研究中，一栋两层钢筋混凝土砌块建筑在完全反向准静态位移控制荷载下进行了破坏测试。该建筑的抗震系统 (SFRS) 总共由八个结构墙组成，其中四个墙沿荷载方向排列，不对称放置，导致刚性中心与楼板质心的偏心约为建筑宽度的 20%，根据弹性分析进行评估。其他四个正交墙围绕建筑物地板质心对称放置，为建筑物提供扭转约束。因此，本文的重点是评估扭曲作为系统级方面对建筑物延展性能力及其墙体构件的延展性和强度要求的影响。本文介绍了建筑物 SFRS 和墙体配置和特征的详细信息以及主要测试观察结果和结果。接下来是安娜...
AbstractIn this study, a two-story reinforced concrete block scaled building was tested to failure under fully reversed quasi-static displacement-controlled loading. The building’s seismic force-resisting system (SFRS) consisted of eight structural walls in total, with four walls, aligned along the loading direction, placed asymmetrically to result in a center of rigidity eccentricity from the floor center of mass of approximately 20% of the building width, evaluated on the basis of elastic analysis. The other four orthogonal walls were placed symmetrically around the building floor center of mass to provide torsional restraints to the building. As such, the focus of the paper is on evaluating the influence of twist as a system-level aspect on the ductility capacity of the building and the ductility and strength demands of its wall components. This paper presents the details of the building SFRS and wall configurations and characteristics and the main test observations and results. This is followed by ana...
