【摘要】 在索拱结构的基础上添加上部斜拉系统则构成了斜拉索拱结构,因此两种结构呈现出不同的受力特性。本文基于实际的工程背景,借助ANSYS建立斜拉索拱结构与索拱结构的有限元分析模型,在四种相同荷载工况作用下,对静力性能和动力性能,进行了结构参数的比较分析,得出了两者在力学性能的异同。结果表明斜拉索拱结构的受力特性优于索拱结构。更多还原

【Abstract】 Based on a cable-arch structure,stayed systems are introduced to a stayed cable-arch structure.Therefore,there are different forced performances between two types of spatial structures.In this paper,the comparisons between stayed cable-arch and cable-arch structure,based on some practical project,using the ANSYS program,establishing two numerical models,including static performance and dynamic performance,are carried out under the same loads.According to the results,the similarities and differences of mechanic performance are summed up,which present that mechanic performances of the stayed cable-arch structure are superior to the ones of cable-arch structure.更多还原
