摘要:
为研究分布筋间距对型钢混凝土剪力墙抗震性能的影响,设计了4个矩形截面型钢混凝土剪力墙试件(其中1个为不带暗撑的普通剪力墙对比试件,3个为带X形暗撑的型钢混凝土剪力墙试件),进行了低周反复荷载试验。结果表明:型钢混凝土剪力墙试件的承载力随着分布筋间距的增大而减小,其分布筋间距为100,150,200 mm的试件承载力较对比试件分别提高了66.8%,45.9%和41%;型钢混凝土剪力墙试件的延性随着分布筋间距的增大而呈线性降低趋势,其分布筋间距为100,150,200 mm的试件延性系数较对比试件分别提高了27.8%,29.2%和11.3%;试件的分布筋间距越小其裂缝越细密,沿暗支撑走向分布越明显,塑性铰范围越大,耗能能力越高,抗震性能越好。
Abstract:
In order to study the impact law of distributed reinforcement spacing on the seismic behavior of steel reinforced concrete shear wall, four rectangular section steel reinforced concrete shear wall specimens (one of them was a common shear wall specimen without profile steel for comparison, the remaining three were test shear wall specimens with X-shaped steel concealed bracing) were designed for experimental study under low frequency cyclic loading. The results show that the bearing capacities of specimens decrease as the distributed reinforcement spacing increases, when the distributed reinforcement spacing is 100,150 and 200 mm,compared with the contrast specimen, the corresponding bearing capacity improves by 66.8%, 45.9% and 41%, respectively. When the distributed reinforcement spacing increases, the ductility of steel reinforced concrete shear wall specimens decreases linearly. Compared with the contrast specimen, when the distributed reinforcement spacing is 100,150 and 200 mm, the corresponding ductility improves by 27.8%,29.2% and 11.3%, respectively. When the distributed reinforcement spacing is smaller, the cracks appear more and denser, the range of plastic hinge is wider, the earthquake energy dissipation capacity is higher and the seismic performance is better.
