| 摘 要： | 我国混凝土结构工程中目前应用的非预应力钢筋强度为300~400MPa,比发达国家低1~2个等级,结构材料用量偏大,消耗了过多的资源和能源。通过拟静力试验,对两片HRB500级钢筋网轻骨料混凝剪力墙分别进行了在低周期反复荷载作用下受力性能的研究,观测了墙体的整个破坏过程,分析了墙体的强度、底部剪切变形和抗震性能。试验及分析表明,剪力墙具有较大的延性和耗能能力,为HRB500级钢筋用作抗震剪力墙的分布筋提供了试验依据。

| Abstract: | The strength of steel reinforcements used in RC structures in China is now only 300 -400MPa, and is lower than that used in Europe and America, thus more materials and energy are consumed in RC structures. The quasi-static test of two reinforced concrete shear walls with 500MPa steel bars were carried out under horizontal low cyclic loading. The whole destroying process of shear wall, and the properties of strength and shear distortion at base of walls were analysed. The analysis results show that the reinforced concrete shear walls with 500MPa steel bars have better ducitility and energy dissipation, which provide experimental references for design of 500MPa steel bars as their distribution steel. |
