考虑局部损伤的斜交空心板承载能力分析

The Load Carrying Capacity Analysis of Skew Hollow Slab Considering the Local Damage

根据预应力混凝土空心板斜交跨线桥受到车辆撞击后所引起的局部损伤程度,结合横向铰接斜交空心板桥受力特点,建立局部损伤的斜交空心板有限元模型,对其损伤后结构受力性能进行分析,评估车辆撞击引起桥梁结构局部损伤对其承载能力的影响,可为相应的工程实践提供有价值的参考。

According to the local damage degree of pre - stressed concrete skew hollow slab after it was impacted by over - high truck, and considering the mechanics property of skew hollow slab, a skew hollow slab finite element was built to analysis the stress performance considering its Local damage, evaluate the influence of the local damage caused by truck impacting. It can provide some value reference for engineering.
