摘要
本文将宽矮多格室曲线板桥化为跨长相等而刚度不等的等效直线板桥,然后按铰接板法的一般原理导得其荷载横向分布的简化公式,并通过有机玻璃模型试验和文献[1]的理论公式进行了验证,三者基本符合。
In this paper, a wide and shallow curved plate bridge with multicell section has been transformed equivalently into a straight bridge with equal span length and unequal rigidity, then formulas for simplified analysis of transverse load distribution for this equivalent bridge are derived based on the principle of a hinge-jolnted plate method. The calculated results and the results from loading test of a perspex model bridge and that from formulas referred to in the reference [1] accord well.
