摘　　要：为解决墙柱的根部封堵及墙柱连接问题,研究提出了基于角钢的根部封堵方法,并对不同连接方式的墙柱结构抗剪性能进行了分析。试验结果显示,试件WC1的正向峰值载荷、反向峰值载荷和开裂载荷最大,但当其达到峰值载荷后,承载力下降最大,下降了318 kN。而试件WC6在达到峰值载荷后的承载力下降最少,仅下降了200 kN。上述结果表明,整体浇筑的剪力墙柱虽然承载能力更好,但其延性较差,而装配式的剪力墙柱具有更好的延性。A root sealing method based on angle steel was proposed to solve the issues of wall column root sealing and wall column connections.The shear performance of wall column structures with different connection methods was analyzed.The experimental results show that specimen WC1 has the highest forward peak load,reverse peak load,and cracking load,but when it reaches the peak load,the bearing capacity decreases the most,by 318 kN.And the bearing capacity of specimen WC6 decreased the least after reaching the peak load,only by 200 kN.The above results indicate that although the overall pouring of shear wall columns has better bearing capacity,their ductility is poor,while prefabricated shear wall columns have better ductility.
