【摘要】 本文在样条函数与“比拟正交异性板”理论相结合的基础上提出“钢筋混凝土肋梁桥比拟正交异性板分析的样条有限点法”。该方法便于采用电子计算机进行分析,编写程序简单,需要的计算机容量小,采用PC-1500袖珍计算机就可对一般钢筋混凝土肋梁桥进行分析,且不需借助于专门编制的复杂图表,故不受制表范围的限制。实例计算表明,在取m=3的情况下,新方法与偏心压力法或比拟板法相比,其计算精确度已足可满足一般工程设计的要求。更多还原

【Abstract】 In this paper,a“Spline Finite-Points Method for Orthotropic Plate Analysis of Reinforced Concrete T-beam Bridge”is presented on the basis of combining Spline Function and Orthotropic Plate Theory.This method is convenient for carrying out with a computer,simple to prepare computer program,and economic in computing storage.Ordinary reinforced concrete T-beam bridges can be easily analysed by a Sharp PC-1500 Pocket Computer without relying on special prepared tables and complet design charts,therefore,the analysis will be not confined by the table values.A computed example indicated that with m=3,compared with the Eccentric Compression Method and the Orthotropic Plate Theory,the accuracy of the new method can well satisfy engineering design requirements.更多还原
