Six 1/2 scaled, single-storey, one-bay frame specimens were tested in this study to investigate the seismic behavior of masonry infilled reinforced concrete (RC) frames subjected to lateral loading. The variables investigated include types of masonry and types of openings. The crack patterns, failure modes, load-displacement hysteretic loops, stiffness degradation, and energy dissipation capacity are presented and discussed. It is found that the infilled wall (with or without openings) could improve the behavior of RC frames significantly. Moreover, as expected, the infilled frame with higher strength masonry performed better than those with relatively low strength masonry. Furthermore, the openings may detriment the stability of the infilled walls. The concentric widow opening has worse effects than the eccentric door opening. The proposed analytical model could determine the load resisting capacity of bare frame and infilled frame with reasonable accuracy.

不同填充砌体钢筋混凝土框架抗震性能试验研究

在这项研究中测试了六个 1/2 比例的单层单间框架试样，以研究砌体填充钢筋混凝土 (RC) 框架在横向荷载作用下的抗震性能。调查的变量包括砖石类型和开口类型。介绍并讨论了裂纹模式、失效模式、载荷-位移滞后环、刚度退化和能量耗散能力。发现填充墙（有或没有开口）可以显着改善 RC 框架的行为。此外，正如预期的那样，高强度砌体的填充框架比强度相对较低的砌体表现更好。此外，开口可能损害填充壁的稳定性。同心寡开比偏心开门效果更差。
