Deck 강성비에 따른 강판형교의 구조거동에 관한 연구 = A Study on the Characteristic of Structural Behavior on Steel Plate Girders Varying the relative stiffness Coefficent of Deck

다국어 초록 (Multilingual Abstract)

In recently, according to enlargement the application of steel bridges, we have a concerned with composite bridges. In order that the steel girder and the concrete slab act as a composite structure, the connectors must have adequate strength and stiffness. If there are no horizontal or vertical separations at the interface, the connectors are described as rigid, and complete interaction can be said to exist under these idealized circumstances.
The response characteristic of composite plate girders subject to live loads were investigated using the 3-dimensional finite element analysis. Also, this paper propose the characteristic of structural behavior on steel plate girders as a 3-girder systems, such as bending moment, deflection, and natural frequency of composite gider bridge.
In this study, in order to evaluate the effect of relative stiffness coefficient, 8 types of case according to compressive strength and height of concrete slabs applied to analysis models.
