| Abstract: | The paper deals with the environment-stimulated and vehicle-stimulated dynamic tests carried out for Guangming steel-concrte composite continuous beam bridge in Fuzhou.The theoretical results by finite element software coincide with the test results in situ.And the parameters in regard to the composite action,cross brace effect and external prestressing etc.are analysized for further research of dynamic behavior and design of the type of composite continuous beam bridge. |

| Keywords: | steel-concrete composite continuous beam dynamic response experiment finite element parametric analysis |
