Title

Behaviour of Pile under Machine Induced Vibrations in Kolfe, Addis Ababa Ethiopia

Abstract

The results of an experimental investigation to study the response of short piles subjected to horizontal dynamic excitation has been reported herein. Four cast in-situ RCC short piles of length 2 m and diameters of 0.20 m, 0.30 m, 0.40 m and 0.50 m were cast for this investigation. This resulted in L/d ratios of 10, 6.67, 5 and 4 respectively, thus satisfying the L/d ratio criteria for short piles i.e. it should be less than 10. The piles were cast in a silty sand deposit. To generate horizontal sinusoidal vibrations a motor-oscillator assembly was used. Four foundation bolts were cast into the pile cap to enable the mounting of a motor-oscillator assembly. For each pile, acceleration-frequency records were analysed to obtain resonant frequency of the soil-pile system and shear strain at ground level. Using this data, a procedure has been developed to obtain damping ratio and stiffness of the soil-pile system. Conclusions have been drawn relating (i) Exciting force level and resonant frequency, (ii) Soil-pile stiffness and strain level and (iii) System damping and strain level, considering each pile individually. The influence of L/d ratio on the dynamic response of the soil-pile system has also been demonstrated.

Key Words

short pile, forced horizontal sinusoidal vibrations, soil-pile stiffness, damping ratio.
