摘要:
本文研完的主要目的在于探讨连续弯箱梁桥在特定的荷载情况下的各种受力特征和变形情况。试验桥模型是根据加拿大渥太华市的 CyrvilleRoad 桥作为原型的。由试验实测所得的应力、应变值与理论计算值校核,得到了满意的结果;修正后的理论挠度与实测挠度,其误差在6%以内;当宽跨比L/B=8.89时,其挠度的横向分布规律基本上呈线性比例关系。本文系采用“有限条法”的计算机程序进行理论分析。
Abstract:
The purpose of this investigation is to examine the performance of Conti- nuous curved box girder bridge subjected to various specified loading conditions. The experimental model follows the prototype of The Cyrville Road Bridge in Ottawa,Canada.After careful considerations,it was decided to adopt a 1/24 scale aluminum and microeoncrete deck model. Various loading conditions were applied to the bridge model and results of stresses and deformations at different controlled cross sections are compared with corresponding theoretical values obtained using a finite strip analysis. The results indicate that experimental deflections are in close agreement with those obtained by finite strip method with the maximum discrepancy not exceeding six percent. The transverse distribution of the deflection bears distinct linear behavior for ratio of"torsional span—width"L/B=8.89.Theoretical and experimental values of stresses also show good agreement.
