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...
متن کاملEffect of Pile Foundation on Natural Frequency of Soil Layer
Free vibration of soil often occurs during earthquakes. Since the vibration caused by earthquake does not have (steady state harmonic vibration) continuity, the alluvium vibrates with its natural frequency between two natural seismic waves. This study evaluates the effect of piles on the period of free vibration of a soil layer using numerical method. In the first stage, using analytical equati...

متن کاملSeismic 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...
متن کاملDynamic 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...
