摘要
介绍了正在兴建中的某大桥设计方案的模型试验设计原则、相似常数的选取与确定,采用三维空间有限元模型进行计算,并从理论上分析了结构内力和位移,确定了模型桥的试验控制荷载。
This paper presents the design principles, selection of similarity constants for model tests of conceptual design of a doubledeck concretefilled steel tube arch bridge being constructed, and also describes calculations with 3dimensional spatial finite element model, theoretic analysis of the structural internal stress and displacement, and determination process of control load for tests of the model bridge.
