摘要
以空间桁架模型为基础,推导出预应力混凝土箱梁在弯、剪、扭作用下破坏模式的判别准则,通过试验研究,对预应力混凝土箱梁在弯、剪、扭作用下的强度计算作了进一步探讨。
An attempt is made in this paper to propose the identification criteria for the failure model of prestressed concrete box beams under the combined action of torsion .bending and shearing based on space truss models. According to the experiments performed on prestressed concrete box beams,their strength is further analysed.
