Full-Scale Tests on Seismic Behavior of RC Frames Infilled with Hollow Bricks

摘要

摘要:为了研究空心砖填充墙钢筋混凝土框架结构的抗震行为，进行了1榀足尺空心砖完全填充、1榀足尺带洞口的单层单跨空心砖填充RC框架结构模型的水平低周循环荷载加载试验，研究了空心砖填充RC框架结构的破坏形式、滞回特性及位移延性等试验指标.在此基础上，结合国内外大量单层单跨填充墙RC框架模型的试验数据，分析了洞口对填充墙RC框架极限抗侧承载力和初始刚度的影响，给出了相应的折减系数计算式.研究结果表明：与带洞口的RC框架相比，完全填充的RC框架的水平峰值荷载在早期加载阶段最少可增加70%；随着填充墙破坏程度的加大，当层间位移角达到1%时，两者水平峰值荷载基本相等；洞口降低了填充墙RC框架的抗侧承载力，但结构的变形能力得到了改善，填充墙的开裂及破坏明显减轻.

Abstract:In order to study the seismic behavior of RC frames infilled by hollow bricks, full-scale tests of one-story single-bay hollow bricks infilled frame structure and one-story single-bay hollow bricks infilled frame structure with the opening under low cyclic reversed loading were carried out. Then, the indexes were studied including failure modes, load-displacement hysteretic loops, skeleton curves, bear capacity, displacement ductility, energy dissipation, strength degradation and rigidity degradation. Besides, according to test data from the literatures on one-story single-bay hollow bricks infilled frame structure, the reduction formulae for describing the effects of the openings on strength and rigidity degradation were also proposed. The experimental results show that the peak load of the frame without window and door is increased by 70% at early loading stage in contrast to the frame with window and door, and the peak loads of two structures will become much closer after story drift ratio reaches 1%. It can be found that the openings in infills reduce the ultimate bearing capacity, whereas the structural deformation capacity improves greatly. As a result, the damage of infills lessens.
