摘要
预张力斜拉索拱结构体系在索拱结构的基础上添加了上部斜拉系统,因此呈现出不同的力学性能。通过对预张力斜拉索拱结构与索拱结构在相同荷载工况作用下,结构的内力、位移和支反力的参数比较分析,得出两者在静力性能的异同。结果表明,预张力斜拉索拱结构的静力性能优于索拱结构。
Based on a cable-arch structure,stayed systems are introduced to a stayed pre-tensioned cable-arch structure.Therefore,there are different mechanical performances between two types of spatial structures.The comparison between stayed pre-tensioned cable-arch and cable-arch structure,including structural forces,displacements and reactions,is carried out under the same loads.Based on the results,the similarities and differences of static performance are summed up,which indicates that static performances of the stayed pre-tension cable-arch structure are superior to those of cable-arch structure.
