预应力混凝土曲线连续梁桥的计算机辅助分析

The Computer Aided Analysis of Curved P. C. Continuous Girder Bridges

本文提出了预应力曲线连续梁桥的数值分析方法。该方法以空间曲梁理论为基础,从根本上解决了曲线梁桥中预加力荷载的空间计算问题。作者编制了一套实用性很强的计算机程序,并配有计算机绘图。文中的算例讨论了预应力曲线连续梁桥的受力状态以及支座约束应注意的一些问题。

In this paper, a numerical analysis of curved P. C. continuous girder bridges, whichis based on the space curved girder theory, is proposed. The problems of the space calculation of pre-stressed forces in curved bridges could be radically solved by this method. The authors have programed a practical computer program with the computer graphics. In theexample, the authors have also discussed the distribution of the internal forces in the curvedP. C. continuous girder bridges and some problems that should come under the designer's notice.
