应用对简支悬索桥承受横向风载时的均等分配法原理 ,增补了对三跨连续悬索桥受横向风载时的近似计算公式。为了校核它的精度 ,首先对算例的三维空间结构进行平面模拟 ,然后应用平面杆系有限元法程序对它进行了计算 ,两种方法的计算结果 ,比较接近 ,因此 ,它们均具有实用价值 By applying the principle of equal distribution when the simple supported suspension bridge is subjected to lateral wind load, the approximate formula for calculating the transverse wind load on the three-span continuous suspension bridge is added. In order to check its accuracy, the three-dimensional space structure of the study is first plane-simulated, and then calculated using the plane-rod finite element method. The calculated results of the two methods are relatively close, and therefore they are all practical value
