DYNAMIC CHARACTERISTICS OF A PILE GROUP FOUNDATION : Forced vibration tests and correlation analyses of full scale pile group foundations

A comparative study on pile group and piled raft foundations (PRF) behavior under seismic loading

Study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. The process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. By means, ABAQUS software was applied for the finite elem...

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...

Study on Load-Bearing Characteristics of a New Pile Group Foundation for an Offshore Wind Turbine

Because offshore wind turbines are high-rise structures, they transfer large horizontal loads and moments to their foundations. One of the keys to designing a foundation is determining the sensitivities and laws affecting its load-bearing capacity. In this study, this procedure was carried out for a new high-rise cap pile group foundation adapted to the loading characteristics of offshore wind ...
