承重轻砌块开洞墙体抗震性能的研究
|
摘要
利用有限元软件ANSYS对蒸压加气混凝土承重砌块开洞墙体的低周反复水平荷载试验进行了模拟分析。比较了此类墙体的水平配筋方案和混凝土配筋条带方案的抗震性能;最后,提出了在不同的竖向正应力下适合于此类开洞墙的配筋方式。
Horizontal low cyclic loading experiments of autoclaved aerated concrete block bearing walls with opening are simulated by ANSYS.On such basis, the seismic behavior between the horizontal reinforced walls and the walls with reinforced concrete slab is compared.Finally,the style of reinforcement under different vertical normal compressive stress is proposed.
