A Study on Lateral Resistance of Finned Piles in Sands

Dynamic Soil Structure Interaction of a High-Rise Building Resting over a Finned Pile Mat

“…Since lateral resistance is of higher concern when dealing with the effects of an earthquake on a structure, it is responsible for causing more intense levels of damage; hence, the sub-structure of a multi-story building must be innovative enough to resist these detrimental effects, which are caused by high-intensity vibrations. From the recent research on finned piles, it has been noted that they provide higher levels of lateral resistance than conventional piles in the case of offshore foundations [9,10] and onshore foundations [11,12]. The finned piles also work effectively under a combined load, and fin shape greatly influences the behavior of the pile [12,13].…”

The level of lateral resistance in finned piles is largely influenced by fin-length, rather than fin-width [11,12,14] or fin-orientation [15,16].…”

“…Moreover, finned-piles with smaller diameters are capable of withstanding lateral loads that are equivalent to that of regular piles with larger diameters [14]. The finned piles with rectangular fins provide greater levels of resistance than triangular fins [11,12,16,17]. Finned piles not only increase lateral resistance, but they also decrease lateral deformation; thus, both the criteria (load and serviceability) of the limit state design, as per IS:456-2000 [18], are satisfied [19].…”

“…According to previous research, a finned pile foundation is one of the proven innovative techniques [19] that aids the resistance of the static latera load [9][10][11][12][14][15][16][20][21][22], cyclic loads [23], and combined loads [13]; hence, the present study aims to quantify the seismic response of a 25-story building, with a shear-walls facility, supported with a conventionally piled-raft (RP-Mat). This study also attempted to reduce the seismic response of a similar building with the finned-pile mat system (FP-Mat), while numerically considering the soil-pile structure interaction by creating a SSI model using ABAQUS-CAE software.…”
