between two tendons 中文意思是什麼
between two tendons
解釋
兩筋間-
The study in the paper starts with beam distortions, and it treats the plastic deformation area as pure bending sect, rest of the beam as rigid bodies. according to different shapes of the external tendons, it divides into three structural forms familiar in projects, that is the beams with no deviator, with a deviator and with two deviators, and studies the relation between the deformation of the external prestressing tendons and that of the beams, and derives the formulas of the ultimate stress increment of external tendons. in the formulas, the ultimate angle corresponding to half of the plastic deformation area is considered as a variable parameter
本文首先從梁極限狀態下的變形入手，將塑性鉸區看作純彎段，將塑性鉸以外的區域看作剛體，按照體外預應力筋的形狀不同，分工程中最常見的三種體外結構形式，即無轉向塊的直線型體外筋混凝土梁、具有一個轉向塊的單折線型梁和具有兩個轉向塊的雙折線型梁，研究體外預應力筋變形和梁體的變形間的關系，推導出以極限狀態下塑性鉸區之半對應的轉角為參數的計算體外預應力混凝土簡支梁以及連續梁的體外筋應力增量計算公式，並進一步求得梁的極限承載力。 -
At first, the soft of bridge structure, gqjs, is used to calculate the structure of prestressed concrete continuous beam bridge and the deformation and stress of the concrete box beam are given out ; then by measuring and analyzing the datum of the stress in the prestressed steel rope and the stress of section in the concrete box beam, this article presents two ways to identify the reasonable friction deviation factor k between longitudinal prestressed tendons and the wall of duct ( indirectly and directly ), and discover the regular pattern of prestressed friction loss
首先運用橋梁結構分析專用軟體gqjs對預應力混凝土連續梁橋進行結構計算，得到了各施工工況下混凝土箱梁的撓度和截面應力；然後給出了識別引起結構預應力損失的孔道偏差系數k的兩種方法（間接法和直接法） 。通過對測得的預應力索沿程應力和混凝土箱梁截面應力數據的分析處理，得到了合理的預應力孔道摩擦偏差系數及預應力摩阻損失規律。
