摘要:
以收集的国内96片装配式钢筋混凝土剪力墙试验数据为基础,对采用规范中现浇剪力墙抗弯承载力设计公式进行“等同现浇”的装配式剪力墙抗弯承载力设计的可靠性进行评估。分析结果表明:规范中抗弯承载力设计公式用于“等同现浇”的装配式剪力墙抗弯承载力设计具有较高的准确度,但其可靠指标未能满足目标可靠指标[β]=3.7的要求。为了达到目标可靠指标的要求,采用可靠指标调整系数0.95对规范中抗弯承载力设计公式进行修正。经分析,修正后的设计公式用于等同现浇连接的装配式钢筋混凝土剪力墙抗弯承载力设计的可靠指标均值达到3.7828,满足目标可靠指标[β]=3.7的要求。
Abstract:
Based on the test data collected from 96 pieces of precast RC shear walls, the reliability analysis of the design of equivalent cast-in-place precast RC shear walls using the flexural load-bearing capacity formula of cast-inplace RC shear walls in the codes was conducted. The analysis results showed that the design of equivalent cast-inplace precast shear walls adopted the flexural load-bearing capacity formula in the specifications with high accuracy, but its reliability index failed to meet the requirement of target reliability index[β]=3.7. To meet the requirements, a reliability index adjustment factor of 0.95 was introduced to modify the current flexural load-bearing capacity formula in the codes. the average value of the reliability index in revised formula for the design of the flexural bearing capacity of equivalent cast-in-place precast reinforced concrete shear walls reached 3.782 8, which well met the requirements of the target reliability index[β]=3.7.
