混凝土-粉煤灰砌块砌体剪力墙的试验研究

本文对混凝土-粉煤灰砌块砌体剪力墙进行了试验研究,试件共2榀,其中一榀是有配筋芯柱的。低周反复水平力作用下的试验结果表明,混凝土边柱与粉煤灰砌体能共同工作,受力特点和破坏形态与剪力墙的相同,具有较好的抗震性能。对比两榀试件的试验结果,表明芯柱可显著提高这种砌体剪力墙的承载力和变形能力。

Experimental Study on Concrete-Fly-Ash Block Masonry Shear Walls

This paper presents the experimental study of the two concrete-fly-ash block masonry shear wall specimens subjected to low frequency cyclic horizontal loading, in which the specimen MW2 is set the reinforced core column centrally.The test results show that the outer concrete column and the inner fly-ash masonry can work together harmoniously as an entirety, the mechanical behavior and the failure forms of masonry shear wall are similar to those of concrete shear wall and these masonry shear walls exhibit good seismic behavior.Furthermore,the test result comparisons between the two specimens indicate that the load bearing capacity and deformation property of such masonry shear wall can be promoted if the core columns are set reasonably.
