钢筋混凝土截面剩余含筋率统计方法对工程的意义

The Significance of the Statistical Methods of Remaining Reinforcement Rate on Reinforced Concrete

在简要介绍钢筋混凝土截面剩余含筋率统计方法的基础上，结合工程实际，采用有限元ANSYS分析程序，对比原配筋率与剩余含筋率70％排架抗震性能，结果表明剩余含筋率70％排架抗震安全不满足规范要求。因此，分析钢筋混凝土工程的现状安全时，应该考虑截面剩余含筋率的影响。

After briefly introduction of the statistical methods of remaining reinforcement rate on reinforced concrete, and in combination with the engineering practide,by using the ANSYS finite element analysis program, comparison with the seismic performance of original ratio of reinforcement and the remaining 70% bent, the results show that the remaining 70% bent seismic safety does not meet regulatory requirements. Thence, when analyzing the security status of the reinforced concrete works, the impact of remaining reinforcement rate should be considered.
