| Abstract: | A butterfly-shape arch bridge in Zhongshan City is a multi-element spatial structure composed of inclined steel arch ribs,curved steel box girder and inclined suspenders,and the structural behavior of the bridge is particularly complicated.To ensure the safety and rationality of the behavior of the bridge and also to verify the reliability of its design and calculation theories,the 1/10 scale model tests have been carried out.In this paper,the general situations of the model tests are outlined in brief,the spatial plate and shell finite element model is established to theoretically analyze the model bridge for the tests,the measurements of the tests under principal load cases are provided and corresponding proposals to the design and construction are made as well. |
