V形支撑连续梁全桥横向刚度有机玻璃模型的试验与分析

Test and Analysis of Plexiglass Model for Lateral Stiffness of Long Span Continuous Girder Bridge with V Supports

介绍了南昆线南盘江大桥大跨度Ｖ形支撑连续梁１／５０比例缩尺的有机玻璃模型试验结果。试验表明，该桥横向自振周期和水平挠跨比的试验值与采用ＳＡＰ程序的计算值符合良好，该桥的横向刚度满足要求。

The lateral stiffness test results of 1/50 scale plexiglass model of the Nanpanjing river long span bridge located in the Nanning Kunming railway line are introduced in this paper.Tests show that the test values of the lateral natural vibration period and the horizontal deflection to span ratio for the bridge agree well with the calculated ones by the SAP program.The lateral stiffness of the bridge fulfills the code requirement.
