摘要:
通过对钢-高性能混凝土组合桥塔节段进行轴压承载力试验,研究了组合桥塔的受力特性.参考相关规范和规程,对组合桥塔的承载力进行了计算.试验和计算结果表明:组合桥塔中混凝土的存在,可以避免或延缓塔壁发生局部失稳,提高结构的承载能力,较钢桥塔具有较大的优势;采用直接叠加的方法得到的承载力较试验值大7.3%,采用DBJ13-51-2003中的方法得到的承载力较试验值大25.3%,前者计算简便,后者可以考虑壁板和混凝土的相互作用,但这两种方法均不能计入壁板局部屈曲的影响;组合桥塔的焊缝和母材应等强,否则会因焊缝破坏而造成整个结构的破坏.
Abstract:
The axial bearing capacity test of the steel-high-performance concrete composite tower section was carried out to study the stress characteristics of the composite tower. Referring to the relevant codes and regulations, the bearing capacity of the combined bridge tower was calculated. The test and calculation results show that the presence of concrete in the composite bridge tower can avoid or delay the local instability of the tower wall, improve the bearing capacity of the structure, and have great advantages over the steel bridge tower. The bearing capacity obtained by the direct superposition method is 7.3% larger than the test value, and the bearing capacity obtained by the method in DBJ13-51-2003 is 25.3% larger than the test value, the former is easy to calculate, the latter can consider the interaction between the wall plate and the concrete, but neither method can be included in the influence of local buckling of the wall plate; The weld and base metal of the composite bridge tower should be equally strong, otherwise it will cause the destruction of the entire structure due to the failure of the weld.
