摘要:
结合某城市一座立交工程匝道高架曲线箱梁桥的工程实例,采用大型有限元分析程序AN-SYS,选取空间梁单元建立动力计算模型,研究了在跨度相同的条件下,曲率半径与角度比值对曲线梁桥动力特性和地震反应的影响。分析结果表明:曲率半径与角度比值是影响动力特性的一个重要参数,且对曲线梁桥的切向刚度、径向刚度和地震反应有较大的影响。
Abstract:
Taking an engineering design case of a curved box-girders bridge,a three-dimensional finite element calculating model for the curved box-girders bridge is set up by means of finite element analysis program ANSYS and the influence of the curved box-girders bridge with the ratio of curvature radius to angle under same span on dynamic characteristics and seismic responrse is researched.The analyzed results show that the ratio of curvature radius to angle are an importance parameter,which affects the dynamic characteristic,and has significant influence on tangential stiffness,radial stiffness and seismic response of the curved box-girders bridge.
