【摘要】 本文对6根区域约束混凝土柱和3根普通井字箍约束混凝土柱进行了周期往复荷载作用下的试验研究,分析了配箍形式及轴压比等因素对构件延性的影响。试验结果表明,区域约束的配箍方式能有效提高构件的延性。另外,通过本次试验还发现适当提高轴压比可以更好的发挥材料力学性能。更多还原

【Abstract】 Experiments were done on 9 concrete columns under low cyclic loading mode.On the basis of formers,the impact of the stirrup forms & axial compression ratio on the ductility was explored.The results indicate that regional confined can effectively improve the ductility of the columns,and Regional Confined Concrete(RCC) columns have excellent properties even under high axial compression ratio.更多还原
