钢筋混凝土构造柱约束砖砌体墙片抗震性能试验研究
|
摘要
为研究钢筋混凝土构造柱对砌体墙片侧向刚度、变形及承载能力的影响,设计并制作3组缩尺砌体墙片模型,并进行拟静力试验。试验结果表明,构造柱与墙体具有相同的变形机制,共同抵抗水平推力作用;端部约束构造柱的存在可有效抑制墙体水平裂缝的发展,并能提高墙体的初裂位移;墙中设置构造柱后,墙体的破坏形式表现出一定的延性破坏特征而非素砌体墙片的剪切破坏模式;设置多道构造柱可有效提高墙体的承载能力及墙体的侧向刚度。
To explore the impact of the reinforced tied columns on the lateral stiffness,deformation capacity and ultimate carrying capacity of the masonry wall,three scaled down masonry wall models were designed and manufactured,and the pseudo-static test were carried out. The results verify that the tied columns and wall share the same deformation mechanism and resist the lateral force together. The development of the cracks are controlled and the cracking displacement is improved because of the tied column. The failure mode shows some ductile behavior but not the pure shear failure mode. The ultimate bearing capacity and the lateral stiffness of the wall are effectively improved in the presence of the tied columns.
