高炉矿渣混凝土剪力墙抗震性能试验研究

Experimental Study on Seismic Performance of bheanng Wall with Blast Furnace Slag Concrete

设计了2个普通混凝土剪力墙试件和4个高炉矿渣混凝土剪力墙试件,对比分析了普通混凝土剪力墙试件和高炉矿渣混凝土剪力墙试件的滞回性能、骨架曲线、位移延性系数与耗能能力,同时对混凝土强度等级、轴压比、配筋率等参数对各剪力墙试件滞回性能、骨架曲线、位移延性系数与耗能能力的影响进行了探讨。结果表明,高炉矿渣混凝土剪力墙试件的抗震性能与普通混凝土剪力墙试件相近,说明高炉矿渣混凝土可以代替普通混凝土用于剪力墙中。

The two common concrete shear wall specimens and four blast furnace slag concrete shear wall specimens are tested to analyze comparatively the hysteretic behavior, skeleton curve, displacement ductility index and energy dissi- pation capability of the two kinds of concrete shear walls. Meanwhile, the influences of various parameters such as con- crete strength grade, axial compression ratio and reinforcement ratio on the four properties mentioned above are studied. The result indicates that the seismic performances of the two kinds of specimens are close, which shows that common con- crete can be replaced by blast furnace slag concrete in the construction of shear walls.
