Dynamic Analysis of Laterally Loaded Piles in Group
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 6
Abstract
This present paper studied the behaviour of the piles in grouparrangedin series subjected to dynamic load due to earthquake. Various combinations of group piles in series like 2 piles, 3 piles and 4 piles are considered for various spacing 2D, 3D, 4D, 5D and 6D, where D is the diameter of the pile. The pile foundation is assumed to be enclosed within cohesion-less soil and soil properties are considered from a live soil report and similarly the load applied is also considered from the same live project report. The models are analysed in the finite element method based software naming STAAD Pro. to obtain the responses such as deflection, axial force, shear force and bending moment for piles in group. While pile cap is analysed for bending moment in ‘x’ and ‘y’ direction. It is seen that deflection increases till a certain length of pile and then reduces as the length increases for all cases and it is also noticed that deflection is more for the closely placed piles. Similarly it is noticed that axial force increases as the length increases for all cases. However, bending moment and shear force decreases as the length of piles increases for all cases and maximum value isobserved for closely placed piles.
