预应力砼梁的应力损失(σs2)的新解——在锚具变形、钢筋回缩和接缝压缩引起的条件下
New Solution of Stress Loss σs2 for Prestress Concrete Beam——Under the Condition of Anchor Deformation, Contraction of Reinforcing Streels and Compress of Juncture
【摘要】 本文根据正反摩阻力相等原理,对σs2及其分布长度 S,导出有别于文献[1]的表达式。其结果概念合理,形式简单,计算方便,精度可靠。并以实例分析对比加以论证。
【Abstract】 According to the equilibrium theory of positive and negative friction,this paper derives a new formula of σ_ and its distribution length which differs from the reference[1].The result pos- sesses reasonable concept,simple form,convenient for calculation and reliable precision.The paper makes an analytic comparison and demonstration by an example too
