摘要
采用有限元软件Midas/Civil,对不同铰缝形式的空心板按照不同损伤特征进行活荷载受力分析,建立空心板铰缝损伤分级评价方法,并通过荷载试验验证了损伤分级评价方法的可行性,为空心板铰缝损伤程度整体评价提供了参考,有助于对铰缝损伤进行预防性养护决策。
The finite element software MIDAS/Civil is used to analyze the live load of hollow slab with different hinge joints according to different damage characteristics.The damage grading evaluation method for hinge joint of hollow slab is established.The feasibility of the damage grading evaluation method is verified through the load test in order to provide the reference for the overall evaluation of the hinge joint damage degree of hollow slab,which is conductive to make the preventive maintenance decision for the damage of hinge joint.
