摘要(Abstract):

通过在周期反复荷载作用下高强混凝土柱的受力性能试验,考察了轴压比、混凝土保护层厚度等因素对柱延性等性能的影响.结果表明:柱的延性随轴压比或混凝土保护层厚度的增加而减小.综合本次试验和以往对高强混凝土柱的试验结果,提出了在不同设计轴压比下的抗震最小配箍特征值.
The influence of the concrete cover depth and the axial force ratio on the ductile behavior of HSC columns is examined in this experimental investigation. It has been revealed that the ductility of the columns is reduced with the increasing of the axial force ratio and the concrete cover to reinforcement. By combining the test results of this research and previous results obtained in Tsinghua University, an empirical formula of ultimate drift ratio is proposed and the minimum steel indices of the hoops in terms of different design axial force ratios and earthquake resistant grades are recommended.
