摘要
在总结和分析组合索塔结构形式的基础上,依据变形协调原理推导了组合索塔锚固区主要构件承担水平力的计算公式,并推导了计算主要构件内力的一般算式.结合一实际工程进行了组合索塔锚固区水平受力分析的足尺模型试验,得到了主要构件的应力分布规律.通过与试验结果进行对比,验证了本文提出的公式的准确性.
Based on a summary and an analysis of the configuration in composite cable-pylons,the expression for calculating the horizontal force burdened by the main members of composite cable-pylon was deduced according to the deformation compatibility principle;and the expression for calculating the inner force of the main members in composite cable-pylon was deduced too.The full scale model tests were made to analyze the horizontal mechanical behavior of composite cable-pylon according to an actual project and the stress distribution patterns of main members were obtained.Comparing to the tests results,the proposed accurate of the method was testified.
