摘要
对于宽度与跨度之比(B/L)>0.5的宽桥,用G-M法进行横向分布计算,可得到较为精确的结果,但利用计算图表手工计算则较为繁琐.笔者尝试利用MathCAD软件,计算其横向分布影响线,并给出算例,可供桥梁工程技术人员及高校师生参考.
For wide beam bridges （i.e.B/L〉0. 5） under transverse loading-distribution, the influence line calculation result its using G-M theory is relatively accurate but the manual calculation process based on the calculating graphs is much heavy. In this paper, a program base on the G-M theory was written using MathCAD to calculate the above influence line. One example was given to show the validity and the convenience of this program.
