| Abstract: | 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. |
