| 摘 要： | 针对钢-高性能混凝土组合桥塔节段进行了轴心受压试验,研究组合桥塔的受力性能,得到了模型破坏时的承载力和破坏形态,分析了其应变及变形规律。参考相关规范和规程,对组合桥塔的承载力进行了计算,并在试验基础上提出了组合桥塔承载力的计算方法。结果表明:壁板的局部失稳对于组合桥塔的承载力影响较大;在计算组合桥塔的轴压承载力时,需根据壁板局部失稳的情况加以区分,可以采用矩形钢管混凝土组合结构规范中的公式或本文提出的方法进行计算。

| Abstract: | An axial compression test was practiced on a steel and high-performance-concrete composite bridge tower segment in order to study the structure behavior of the composite towers.From the test,the limit load-capacity and failure mode of the specimen were obtained,and the regularity of the strain and deformation were analyzed.The limit load-capacity was calculated according to the related codes of China and other countries,and two other calculate methods were proposed based on the test.The result shows that th... |
