SEISMIC RESISTANCE OF REINFORCED CONCRETE INTERIOR PILE CAP USING PRECAST PILE

Analysis Method for Laterally Loaded Pile Groups Using an Advanced Modeling of Reinforced Concrete Sections

A Boundary Element Method (BEM) approach was developed for the analysis of pile groups. The proposed method includes: the non-linear behavior of the soil by a hyperbolic modulus reduction curve; the non-linear response of reinforced concrete pile sections, also taking into account the influence of tension stiffening; the influence of suction by increasing the stiffness of shallow portions of so...

Seismic Bearing Capacity of Strip Footings on Pile-Stabilized Slopes

This paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. The resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. This comparison indicates an acceptable agreement. The variants of the study incl...

Dynamic Interaction of Soil-Pile-Structure under Seismic Action

Due to randomness of seismic load, it is difficult to predict the complexity of the soil, pile, structures and their system. Presently, there isn’t a better way to explain and simulate the dynamic interaction of soil-pile-structure completely and precisely. Based on the stiffness expressions of interaction, the improved physical and mathematical models are setup to reflect the basic mass, stiff...

Seismic Retrofit of Pile Group Foundation with Thickened Caps

The case studied in the paper proves that thickening the pile cap is an effective seismic retrofit alternative to strengthen a pile group foundation. Unlike the typical seismic retrofitting of foundation, the proposed method eliminates the need to drive long piles into existing bridge substructures, substantially reducing cost, construction time and traffic interruption. The method thickens the...
