摘要
为了揭示型钢高强混凝土(SRHC)短肢剪力墙的破坏机理和抗震性能,设计了6个SRHC短肢剪力墙试件,并进行低周反复加载试验。研究结果表明:型钢高强混凝土短肢剪力墙根据剪跨比的不同有剪切斜压破坏和弯曲-剪切破坏两种破坏形态,承载能力高,刚度稳定性好,极限转角大于1/100,滞回曲线呈梭形,位移延性较差,抗震耗能性能比普通型钢混凝土构件的差,与普通钢筋混凝土构件相当。
In order to reveal the seismic behavior of steel reinforced high strength concrete（SRHC） short pier shear wall,6 specimens were designed for low cyclic reversed loading test.Through the test,the failure patterns and bearing capacity are obtained.Experimental study results show that the major failure modes of steel reinforced high strength concrete short pier shear wall are shear diagonal compression failure and bending-shear failure.SRHC has large bearing capacity,stiffness and ultimate rotation capacity,but the displacement ductility and excellent seismic energy dissipation performance are less than the normal steel reinforced concrete.
