摘要
通过对多根区域约束混凝土柱和普通井字箍约束混凝土柱的实验分析,研究了区域约束混凝土柱在高轴压比下的抗震性能,主要比较了区域约束混凝土柱与普通约束混凝土柱之间延性系数、滞回曲线、粘滞系数的差异。结果表明,区域约束混凝土在高轴压比情况下,仍能满足现行国家规范对混凝土柱抗震性能的相关要求。
Through experimental analysis on various regional restrained concrete columns and ordinary ribhed reinforced concrete columns, it studies aseismatic performance of regional restrained concrete under high axial compression ration, and mainly makes a comparison between regional restrained concrete column and ordinary, ribbed concrete column on ductility coefficient, hysteresis curve, and viscous coefficient. Results show that: under high axial compression ration, regional restrained concrete can still meet the current national norms about aseismatic perform- ance of reinforced concrete columns.
