矩形实心公路桥墩延性性能影响因素初步研究

Primary Study on Influence Factors to Ductility Performance of Rectangular Solid Road Bridge Pier

简要介绍了延性的几个基本概念,对进行P-M-分析的步骤作了说明,对轴压比、配箍率和纵筋率等3因素是如何影响矩形实心公路桥墩位移延性系数进行了深入的分析和研究。

This paper gives a brief introduction to several basic concepts of ductility, and describes steps in carrying out P-M-φ analysis. It pays deep study and research to how the 3 factors of axle load ratio, reinforcement ratio and longitudinal reinforcement ratio influence displacement ductility coefficient of rectangular solid mad bridge piers.
