This study describes an experimental and numerical investigation on the seismic behaviour of masonry infilled hinged steel frames with openings. Experimental tests of six half-scaled, single-storey and single-bay specimens including one bare hinged steel frame, one solid infilled hinged steel frame, and four masonry infilled hinged steel frames with different opening sizes were carried out under lateral cyclic loading. The cracking patterns, failure modes, hysteretic behaviour, characteristic loads and displacements, stiffness degradation and equivalent viscous damping ratios of these specimens were compared. Furthermore, detailed three-dimensional finite element (FE) models of test specimens were developed in the commercially available FE code ABAQUS, and a series of nonlinear pushover analyses were performed. In particular, the lateral load–displacement relationships of test specimens were numerically simulated and validated against the experimental results. In addition, the mechanical behaviour of infilled walls under lateral loading was investigated.

这项研究描述了带有开口的砌体填充铰链钢框架抗震性能的实验和数值研究。在横向循环载荷下，对六个半尺寸，单层和单间的标本进行了试验，包括一个裸露的铰链钢框架，一个实心填充的铰链钢框架和四个砖石填充的铰链钢框架，它们具有不同的开口尺寸。比较了这些试样的开裂模式，破坏模式，滞后性能，特征载荷和位移，刚度下降和等效粘性阻尼比。此外，在市售的FE代码ABAQUS中开发了详细的试样三维有限元（FE）模型，并进行了一系列非线性推覆分析。特别是，数值模拟了试样的横向载荷-位移关系，并根据实验结果进行了验证。此外，还研究了侧向荷载作用下填充墙的力学性能。
