摘要
为研究结构设计参数对下承式梁拱组合体系桥的结构力学特性的影响,采用ansys有限元程序计算分析矢跨比、拱肋与梁刚度比、吊杆间距及位置等关键结构参数对桥梁结构受力的影响,探讨上述参数相对较优的方案,可供设计人员参考。
To study the impact of structure design parameters on through arch-beam composite bridge,the paper analyzes the impact of key parameters of rise-span ratio,ratio of arch rib and beam stiffness,boom space and position on bridge structure with ansys finite element program,and elaborates superior plans which can provide reference for designers.
