In recent years, Prestressed Concrete long piles are universally adopted. Last year such kind of pile with length up to 27~M have been produced in this country. Now in order to meet the requirements of Shanghai Harlour works and Yangtze River Bridges, we work out a new type of prestressed concrete hollow pile of 36~M long, with a cross-section, of 55 cm square (inner diameter 40 cm.) By using temporary prestressing fittings on pick points with automatic adjustment for prestress, the pile is suitable for two...

In recent years, Prestressed Concrete long piles are universally adopted. Last year such kind of pile with length up to 27~M have been produced in this country. Now in order to meet the requirements of Shanghai Harlour works and Yangtze River Bridges, we work out a new type of prestressed concrete hollow pile of 36~M long, with a cross-section, of 55 cm square (inner diameter 40 cm.) By using temporary prestressing fittings on pick points with automatic adjustment for prestress, the pile is suitable for two points pick, which gives great facilities to handling and transpotation. Besides, 18% of steel saving can still be made. This paper only presents the principle and calculations. The testing results will be given later.

年来预应力混凝土长桩在各国已广泛采用,我国在去年大躍进中亦已试行生产应用,长达27公尺,最近我校预应力混凝土桩科研小组在响应党的的科研结合生产的号召下,为上海码头工程及长江大桥工程进行36公尺的预应力混凝土长桩研究,并提出一种新的型式,既可节省18%的钢筋又可允许用两点吊运,这将给予施工方面极大便和。现在与上海筑港局协作进行试制与试验,兹特将原理部分报导,希望大家提出意见以便修正改进,至其试验报告则将于以后陆续发表。

In the past, camber, of prestressed concrete beam was computed by approximate method, i, e, neglecting the prestressed force applied at both ends of beam. This paper proposes comparatively an exact method of camber calculation, with tendon form of parabola and straight line for comparison. The author tried sucessively to separate prestressed loss between creep of concrete and relaxation as well as slip of tendon. Theoretical formulae for computing these losses are presented in this paper.

计算予应力钢筋混凝土反挠度一般采用近似方法,由于张拉力Hnp所引起反挠度可以忽略不计。本文目的在于推导更精确计算反挠度的公式并考虑予应力钢筋混凝土梁中不同钢丝束的布置方式来进行反挠度计算的比较。同时在管道中未压浆之前推导了计算钢筋混凝土徐变与钢丝滑动与徐舒所引起的予应力损失的公式。

In this paper, the author summarizes first the existing state and some problems on the calculation of crack width and deflection of R. C. beams. Secondly, with the average crack widths calculated by means of the formula recommended in Russion Code, the author compares the max. crack widths measured from some foreign tests, and according to the principles of statistics, gives a discussion about the coefficient for determining the max. crack width suggested by Chinese Code (project). Having pointed out the unreasonable conditions of the summation formula for calculating the crack width of beams subjected to partial long-time loads in Russian Code, the author suggests two synthetic formulas for the calculation of crack width and deflection, by which we can not only eliminate those unreasonable conditions, but also make the calculation much simpler. For the value of ν in the coefficient γ' which is used to calculate the stiffness of doubly reinforced beams, the author suggests a new recommendation and makes a comparison with the experimental deflections to prove that this recommedation is reasonable. Finally, for the corrected coefficients of the moments at supoart to consider the redistribution of stresses in the continuous beams due to cracking, the author also makes a new recommendation, and carries out comparative computation with some measured deflections from tests. At the same time, for some particular loading conditions which may take place frequently in practice, the author prepares curves of deflection coefficients in order to simplify the calculation of deflection of continuous beams in practical designs.

在本文中,首先对国际上关于鋼筋砼受弯构件的裂縫和变形計算的現阶情况和存在的一些問題作了概述. 其次利用苏联規范中的公式計算的平均裂縫寬度与国外的某些試驗中量得的最大裂縫寬度比較,根据統計原理,来討論我国規范草案中建議确定最大裂縫寬度的系数。作者还指出苏联規范中对部分长期載时計算裂縫寬度的总和公式的不合理情况,因此对裂縫計算,也包括变形計算,提出了綜合公式,这不但可消除这些不合理情况,同时計算也簡单些。对双筋梁刚度計算中系数γ′內的ν值,作者提出了新的建議,并和实驗挠度进行比較,証明这一建議的合理性。最后对考虑連續梁由于裂縫所引起的內力重分布时支座弯矩修正系数提出了建議,并和一些实驗結果进行了比較計算,同时繪制了几种常遇到的荷載情况下的挠度系数曲綫以簡化在实际工作中連梁挠度的計算。
