초록

The objective of this paper is to evaluate the structural safety of EG-Frame system resisting the earth pressure from CIP (Cast-in Place Pile). To accomplish the objective, a compression experiment and FE (Finite Element) analysis for the filler joint in EG-Frame were performed and suggested a proper design process. In the experiment, parameters are the width of the composite beam and the size of bearing plate. In FE analysis, total strain crack model was used for the modeling the concrete in the composite beam and CIP. the joint of CIP and composite beam was modeled as a perfect bond condition. From the experiment, it was shown that a separation of concrete composite beam appeared after shear failure when the width increased. The compressive strength depended on the size of bearing plate. However, there was not a trend of stiffness variation even if the size of bearing plate increased. In the case of same bearing plate, the strength decreased corresponding to the increase of width of the composite beam. It is thought that the round shape of CIP contributed the increase of the shear slip between the contact surfaces of the composite beam and CIP when the width increased.
