摘要
针对蓬沱大桥桥面部分的钢筋混凝土梁式构件,分别计算了正截面抗弯极限状态和斜截面极限状态的可靠指标和失效概率,并采用窄界限范围估计法对构件的整体失效概率进行了估算,给出了体系可靠指标值。
In the light of reinforced concrete beam of Liantuo Bridge deck,this paper has studied the reliability index and failure probability of the normal section's bending resistance limit states and the inclined section's shear resistance. At the same time,the system failure probability and reliability index has been obtained by the narrow limit estimation method.
