Nonlinear dynamic response of floating piles under vertical vibration

چکیده
This paper presents the influence of non-linearity on the dynamic response of floating pile foundation subject to vertical vibration. A detailed theoretical investigation of stiffness and damping parameters is made for floating piles with different shear modulus reduction ratio of the weak zone soil. The accuracy of the non-linear analysis for predicting the dynamic response depends upon the choice of boundary zone parameters and the pile separation length. The tip resistance of pile is neglected and comparison of the theoretical curves with the experimental results has been made. In this study it is shown that close agreement between theoretical and measured response curves of floating piles can be achieved by considering precise boundary zone parameter values and separation between pile and soil.

Experimental Studies of Vertical Dynamic Stiffness of Single Floating Piles under Low Amplitude of Dynamic Force
This paper describes the experimental studies of vertical dynamic stiffness of single piles subjected to small amplitude of vibrations with constant dynamic load. The test results were correlated with the static load test results that had been carried out on the same piles. The ratio of dynamic to static stiffness mainly falls between 1.2-1.4. The dynamic stiffness measurements were compared wi...
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...

There are significant number of pile supported wharves around the world and this type of structures are commonly chosen for the construction of new waterfront port facilities. Batter piles have been used for a long time to resist large lateral loads from winds, water waves, impacts and earthquake. Their distinct advantage over vertical piles is that they transmit the applied lateral loads p...
