半形公式-
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。 -
The two kinds of joint connection half - rigidity characteristic about gabled frames are discussed. the criterion among rigid connection, zero rigidity connection, half rigidity connection is determined ; the joint ' s moment and rotation angle curve is analyzed ; the calculation method about joint initial rigidity is brought forward ; the ultimate moment ' s calculation formula is deduced ; the result calculated by the formulas is compared to one calculated by the norm ' s formulas
探討了門式剛架兩種端板節點連接的半剛性特性，確定了節點剛接、鉸接和半剛接劃分的標準；分析了節點受力時的彎矩轉角曲線關系；提出了節點的初始剛度的計算方法；提出了節點極限彎矩的計算公式，並與規范關于節點抗彎承載力計算的結果進行了比較。
