用影响线法计算汽车渡船跳板主梁的强度

Calculation of Flexural Strength for Vehicle Ferry Gangplank Girder through In uence Matrix

汽车渡船跳板主梁断裂破坏时有发生,尽管其破坏机理非常复杂,但弯曲强度不足往往是其主要原因。本文考虑了结构自重及移动载荷共同作用下对33m汽渡跳板的主梁进行了强度校核。

There have been several cases of girder break for vehicle ferry gangplank due to complex factors, the major one of which has come down to the inadequacy of flexural strength of the girder. Taking into consideration of the structure self-weight and the mobile-load-bearing characteristics, this paper attempts to check the strength of 33-meter vehicle ferry gangplank girder.
