摘要
本文提出样条函数-有限元法用于分析具有不同材料、不同截面变化规律的电视塔地震反应,推导了刚性地基上及柔性地基上桩支承电视塔两种情形的计算公式,编制了专用计算程序,于文末给出了电视塔地震反应分析算例,并对计算结果进行了分析讨论,对于电视塔抗震设计具有参考价值。研究表明:本文方法具有输入数据少、计算工作量小及计算精度满意等优点。
This paper presents S.F.M. ( Spline Function Method ) and F. E. M. ( Finite Element Method ) for the earthquake response analysis of TV tower with different materials and different variations of cross sections. Calculating formulas for earthquake response analysis of TV tower on rigid foundation as well as on pile foundation in soft soil medium ( soil-pile-TV tower system ) are derived. Special computer program has been compiled for the purpose of analysis. A numerical example of TV tower using this method with discussions of calculating results has been given at the end of this paper. It has been shown by this research that this method has the advantages of less input data, less amount of computation work and satisfactory precision.
