| Abstract: | This paper analyzes the influences of floor system types of existing concrete-filled steel tube arch bridges on the structural behavior of the bridges.On the basis of analysis,the paper proposes a type of floor system that is to be made continuous by segments and compares the differences of the structural behavior of suspenders of the bridges through theoretic analysis and model tests.The proposed floor system is then verified by measurements of the model tests and finite element calculations,and some of the problems having been found in the tests are also discussed. |
