【摘要】 为了研究非预应力钢筋对预应力FRP筋混凝土梁抗弯性能的影响,本文定义了各种破坏模式,推导了相应的承载力计算公式,对抗弯强度的折减系数进行了分析,并通过文献中的试验数据对设计公式进行了校核,最后对体内有黏结预应力FRP筋混凝土梁的抗弯设计提出了建议.更多还原

【Abstract】 In order to study the influence of non-prestressed steel tendons of the flexural strength of prestressed concrete beams with bonded FRP tendons,this paper defines the failure modes,presents the equations for flexural strength,recommends the strength reduction factors,and the calculated results by the proposed method are calibrated with test data.Finally suggestions for FRP prestressed concrete beam design are proposed.更多还原
