摘要
后张有粘结预应力框架梁端张拉时,承压板下的混凝土会发生局部下陷,沿承压板周边混凝土受剪切作用,呈局部破坏状态。通过工程实践分析,预应力混凝土局部承压破坏的原因,并提出解决和避免这一破坏状态的防治技术。
During beam end tensioning of post'tensioning bonded prestress frame, the concrete around the beating plate is and local concrete under the bearing plate may collapse. This paper analyzed the reasons for local bearing failure of prestressed concrete and proposed relevant methods for solving and preventing the failure defect.
