摘要
通过 3个扁梁柱节点的试验 ,研究了无粘结预应力筋和扁梁宽度对节点破坏形态的影响。在分析其它文献提出的极限抗剪强度计算公式的基础上 ,提出了更为合理的无粘结部分预应力扁梁柱节点极限抗剪强度计算公式。计算值与试验值进行了比较。
Based on the experiment of three flat beam column joints,this paper studies the effects of unbonded prestressed bars and the width of flat beam on the failure forms of the flat beam column joints.The paper proposes more reasonable equations of ultimate shear strength of unbonded partially prestressed concrete flat beam column joints by analyzing with the equations provided by other references.The calculation results are compared with the experiment data.The equations advised by the author can be a reference to the engineering designers.
