【摘要】 引入非线性摩擦的概念,在剖析了现有预应力结构预应力损失模型的不足及分析了预应力损失的作用机理的前提下,建立了预应力损失计算的非线性摩擦模型,并对所建模型进行了验证。从而可更合理地计算大曲率预应力曲线筋的摩擦损失。更多还原

【Abstract】 Against the lack of the friction loss model in existence,the concept of nonlinear friction has been inducted.Based on the analysis of the mechanism of the prestressed reinforcement′s friction loss and the lack of the actual model,a nonlinear friction model has been presented and its feasibility has been proved.Thereby the prestressed reinforcement′s friction loss can be computed more reasonably.更多还原
