摘要
在公路桥梁设计中,风阻力的影响是一个重要的因素。关于风阻力的计算,许多国家的规范中有不同的规定和计算公式。考虑各种地形、桥墩高度和箱梁长度情况下,运用六个国家的不同规范,计算大跨度高墩箱梁桥上的横向风荷载,对采用六个国家规范计算的墩底弯矩和剪力与采用频率域控制的方法计算的弯矩和剪力进行了比较。
Calculating wind resistance is one important process in the design of highway bridges. The current codes of many countries include different rules and formulas regarding the calculation of wind resistance. In this paper,the transverse-direction wind loads on long-span girder bridges with tall piers were calculated using six codes from different countries under various terrain,pier height,and girder length conditions. The pier-bottom shear force and moment results of transverse wind loads calculated using these six codes were compared to those obtained using the buffeting frequency domain method.
