国内杆塔导地线荷载组合程序开发

Development of Load Combination Program for Tower Guide Line in China

通过对规范规定的杆塔导地线荷载组合计算方法的研究,借鉴以往程序的研究成果并进行优化,基于VB.NET语言研发一套完善、高效的可视化操作程序系统。通过将工况组合符号化和逐工况、逐方向进行荷载分配等方法,实现工况组合和荷载分配的快速计算。深入剖析标准荷载向节点荷载的转换过程,详细地介绍工况组合原理、荷载分配原理和程序构成。

The code for loading calculation for transmission tower is analyzed and the relevant programs is researched in this paper,and then an efficient visual operating program system based on VB.net is developed.By the means of symbolization of working states and distributing forces among nodes according to the working condition and loading orientation,the load calculation of conductors and ground wires on tower is realized.In this paper,the conversion process of standard load to node load,the principle for combination and distribution of actions,and the composition of the program are introduced in detail.At last,an example is demonstrated.
