摘要
前期研究表明,采用销键使混凝土小型空心砌块相互咬合,可以有效地提高砌体结构的抗剪强度。在设置芯柱的条件下,可明显地增强砌体结构的抗震性能,是一种新型的砌体结构。通过对4榀在不同竖向荷载作用下的带构造柱的混凝土小型空心砌块墙体进行的低周往复侧向加荷试验,对采用新型结构形式的墙体和普通结构形式的墙体的变形、延性和耗能能力进行对比分析,提出设置构造柱的新型墙体的抗剪承载力试验公式。试验证明:在设置构造柱的条件下,采用新型结构形式的混凝土小型空心砌块墙体的抗震性能要优于采用普通结构形式的混凝土小型空心砌块墙体。结合前期研究得出:这种新型砌体结构可以有效地提高砌体结构的抗震能力,值得进行工程推广实践。
The previous research indicates that by inserting a concrete bolt in the hole can chain the upper block with lower block,the shear strength of the small hollow concrete block masonry can be increased effectively and seismic performance improved.This is a new type of masonry structure.Four small-sized hollow concrete block masonry walls with constructional columns were tested under different vertical loads.The mechanical behaviors were described.The ductility and energy dissipation capacity were analyzed.The shear strength formula of the new-styles block masonry walls was proposed.The experiment shows the seismic performance of new-style block masonry walls is better than the common ones.The research indicates the new-style masonry structure can strengthen the seismic performance of masonry buildings effectively,which can be used in practical engineerings.
