| 摘 要： | 针对工程实际中柱轴压比超限问题 ,利用MonteCarlo法 ,对轴压比限值进行可靠性分析 ,讨论了不同抗震等级 ,不同钢筋强度、纵向配筋率对柱轴压比限值可靠指标的影响。提出在保证柱轴压比的可靠指标不低于现行《规范》的情况下 ,应适当考虑柱纵筋配筋率和配箍率对轴压比限值的提高。

| Abstract: | Focused on the problem of axial compression ratio beyond the limit value in actual engineering,reliability analysis of ultimate axial compression ratio is computed by Monte Carlo method.Influences of variable aseismic rank,reinforcement strength and ratio of longitudinal reinforcement on reliability index are discussed.The enhancement for ultimate axial compression ratio because of longitudinal reinforcement should be considered in a certain when the reliability index is not lower than that of current code. |

| Keywords: | Ultimate axial compression ratio Longitudinal reinforcement ratio Reliability |
