摘要
以某森林公园人行拱桥施工图设计为背景,结合我国人行拱桥设计理念,利用有限元计算数据,从拱高、弯矩、轴力、剪力及自振动力特性分析,确定桥梁的构造尺寸,并通过配筋计算分析其结构优化的合理性,为同类人行拱桥结构设计提供理论依据和分析方法。
Taking the construction drawing design of pedestrian arch bridge in a forest park as the background,and combined with the design concept of pedestrian arch bridges in China,the finite element calculation data are used to analyze the arch height,bending moment,axial force,shearing force and natural vibratory dynamic property,and to determine the structural dimensions of bridge.The reinforcement computation can analyze the rationality of its structural optimization,which provides the theoretical basis and analysis method for the structural design of the similar pedestrian arch bridges.
