为了研究带节能砌体填充墙的RC框架抗震性能，本试验设计了两个两层单跨的RC框架结构模型，分别为带填充墙的RC框架和不带填充墙的空框架，并对其进行了拟静力试验。对带填充墙的 RC 框架的裂缝开展进行了描述，研究了试件的滞回特性、骨架曲线、刚度退化和强度退化，并和空框架进行了对比分析。分析结果表明：填充墙能够提高框架的承载能力和抗侧刚度，但是相应地降低了框架结构的延性；填充墙的存在使得框架结构的强度和刚度退化加快，然而，带填充墙框架的极限刚度仍然较大，表现出较强的抗倒塌能力。

To investigate the seismic behavior of RC frames with energy conservation masonry infill walls,two RC frame models with two-floor single span,one with infill walls and the other without infill walls (bare frame),were tested with the pseudo-static experiment.The cracking distribution of frame with infill walls was described,and the load-displacement hysteretic curves,skeleton curves,rigidity deg-radation and strength degradation were discussed in comparison with the bare frame.The results show that the lateral load-bearing capacity and structural lateral stiffness of the RC frame,but not the ductility, can be increased by infilling walls in the frame.Due to the presence of the infill walls,the rigidity degrada-tion and strength degradation of the frames will be sped up.However,there is still enough stiffness when the RC frame with infill walls is destroyed,which indicates the good resistance to collapse resistance of the frame with energy conservation masonry infill wall.
