Ultimate State of Bridges with Soil-Pile-Structure Interaction under Extreme Earthquakes
This paper is aimed to analytically study the ultimate state of bridges with seismic soil-pile-structure interaction. Since the Vector Form Intrinsic Finite Element method is superior in managing highly nonlinear engineering problems even with fracture and collapse, it is used in this study to predict the failure process of bridges. During an extreme earthquake, soil may undergo plastic behavior, and piles may go through cracking, plastic hinge, even fracture. In this study, several nonlinear soil-spring models are developed to simulate the soil-structure interaction behavior under strong ground motions. Through a series of parametric studies, the failure modes are demonstrated for bridges with pile foundation. The result showed that, both soil and piles went through plastic behavior. It is suggested to analyze bridges under strong ground motions by using nonlinear soil elements for realizing the actual dynamic behavior.
