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。
Preliminary studies have shown that the use of pin to small concrete blocks bite each other, which can effectively improve the shear strength of masonry structures. Under the condition of setting the core column, the seismic performance of the masonry structure can be obviously enhanced, which is a new type of masonry structure. Through the low-side reciprocating lateral loading test of small hollow concrete block with structural columns with different vertical loads under 4 榀 cycles, the wall structure with new structure and the common structure Deformation, ductility and energy consumption were analyzed comparatively, and the test formulas of shear resistance of the new type of wall with structural columns were proposed. The test proves that the seismic performance of the small concrete hollow block wall with the new structure is better than that of the small concrete hollow block block with the common structure when the column is set up. According to the previous research, it is concluded that this new type of masonry structure can effectively improve the seismic capacity of masonry structures and is worthy of popularizing in practice.
