Abstract


In this paper, Angola Jen heat - Multi Highway 7 East # bridge engineering background of steel - concrete composite continuous beam bridge structure performance and design methods to carry out the work of the following aspects : ① According to rely on works at the bridge site specific conditions , through Alternatives , considering the cost , bridge landscape , construction conditions and environmental factors such as climate , under limited conditions choose a reasonable bridge program to draw the corresponding construction program. ② structure-based conceptual design, based on the project 's steel girder segments , shear connectors and pier construction details such negative moment area were analyzed for steel - concrete composite continuous beam bridge features of the local structure of the bridge for detail the corresponding construction process , made ??of flexible and rigid shear bond shear key joint use arrangement , you can reduce the number of prefabricated panels , and can effectively improve the interface of steel beams and concrete shear capacity . ③ the use of large general-purpose finite element software ANSYS, by numerical simulation on rigid shear key is loaded into destruction from the mechanical behavior of the whole process of investigation, analysis of the deformation , stress distribution and load - slip curve , its ultimate capacity parametric analysis of influencing factors , to establish a rigid shear key failure modes presented for reference rigid shear key ultimate strength simplified formula . ④ against relying on the works proposed Bridge Road board structure layout program , and through the finite element software ANSYS discussed separately temperature , shear connectors are arranged in the form and manner Bridge Road board mounting steel - concrete composite continuous beam influence the mechanical behavior .
