Abstract: Seismic performance of bridge structures supported by extended pile-shafts principally depends on the curvature demand in critical regions of the pile below ground level. The equivalent fixed-based cantilever model is ...

Abstract: The lateral performance of large-capacity helical piles is of significant interest. This study presents the results of five full-scale lateral load tests conducted on 6.0 and 9.0 m large-capacity helical piles of shaft ...

Abstract: This paper investigates the structural performance and soil–culvert interaction of large-span precast concrete three-sided culverts (TSCs). Three TSCs with flat top slabs have been instrumented with 30 pressure cells and ...

Abstract: This paper investigates the dynamic response of soil around a laterally vibrating extended pile shaft and its application to the lateral parallel seismic (PS) integrity testing method. Considering the high pile to soil ...

Abstract: Helical piles are currently used to support large compressive loads, which requires accurate evaluation of their bearing capacity. High strain dynamic load testing is increasingly used to determine the capacity of helical ...

Abstract: This paper investigates the structural behavior and soil–structure interaction mechanism of a three-sided culvert (TSC) at service and ultimate load levels. Field measurements were used to verify a two-dimensional (2D) ...

Abstract: The gradation and water content have a significant influence on the resilient modulus of strongly weathered phyllite subgrade. In this study, small-scale plate loading tests were conducted on large cylindrical specimens ...

Abstract: This paper examines the seismic performance of a bridge–helical pile foundation based on the seismic fragility analysis, considering the element fragility of a coupled bridge–soil–foundation system. Nonlinear time history ...
