Shaft Resistance of Piles under Horizontal Force and Overturning Moment

Rocking Response and Overturning of Equipment under Horizontal Pulse-Type Motions

In this report the transient rocking response of electrical equipment subjected to trigonometric pulses and near-source ground motions is investigated in detail. First the rocking response of a rigid block subjected to a half-sine pulse motion is reviewed. It is shown that the solution presented by Housner (1963) for the minimum acceleration amplitude of a half-sine pulse that is needed to over...

Dynamic Response of Single Piles Under Lateral Loads and Earthquakes

Shaft Resistance of Driven Piles Based on CPT and CPTu Results Using GMDH-type Neural Networks and Genetic Algorithms

Cone penetration test is one of the most common in-situ tests for pile analysis given that by its analogy as a model pile, the measured cone resistance and sleeve friction can be employed for estimation of pile unit toe and shaft resistances, respectively. In this paper, group method of data handling (GMDH)-type neural networks optimized using Genetic algorithms (GAs) are used for modelling the...

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...
