连续悬索桥受横向风载的分析

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。

Analysis of Continuous Suspension Bridge Bearing Transverse Wind Load

Applied the principle of equal distribution method for simple supported suspension bridge bearing the transverse wind load, this paper supplements the formula of approximate calculation for three span continuous suspension bridge bearing the same load. In order to prove its precision this paper also gave an example. At first this three dimensional space structure is simulated as a plane structure, and then it is calculated by applying the computer program of finite element method, the results obtainned by the above both methods are more similar. Therefore they have pratical significance.
