Harmonic Response of Pile Groups to Dynamic Loading

Static and Dynamic Lateral Loading of Pile Groups

Interpretation of static pile loading test results and application for design of pile groups

Recent major bridge projects in the Greater Vancouver Area showcase the experience of local geotechnical engineers. Large static pile loading tests have been carried out on a number of these projects including the Pitt River Bridge, Golden Ears Bridge and Port Mann Bridge projects. This paper briefly discusses different analytical approaches to load test interpretation and reviews the approach ...

Dynamic magnification factors of SDOF oscillators under harmonic loading

The magnification factor for the steady-state response of a SDOF system under harmonic loading is described in many structural dynamics textbooks; the well known analytical solution is easily obtained from the solution to the damped equation of motion for harmonic loading. The complete and steady state solutions can differ significantly. An analytical expression for the maximum response to the ...

An Analytical Solution on Size Dependent Longitudinal Dynamic Response of SWCNT Under Axial Moving Harmonic Load

The main purposes of the present work are devoted to the investigation of the free axial vibration, as well as the time-dependent and forced axial vibration of a SWCNT subjected to a moving load. The governing equation is derived through using Hamilton's principle. Eringen’s nonlocal elasticity theory has been utilized to analyze the nonlocal behaviors of SWCNT. A Galerkin method based on a clo...

Torsional Pile Subjected to Transient Loading in Viscoelastic Poroelastic Medium

Considering viscoelastic saturated soil, The transient dynamic response of an elastic pile is studied. The pile-soil system is divided into thin layers, the control equations of the soil are solved respectively by using Laplace transform. Considering the mixed boundary-value conditions at the interface of pile and soil, expression is derived to describe the relationship between the inner force ...

Raft and Pile Foundations under Cyclic Loading

The paper presents typical phenomena which can occur due to cyclic loading in granular soil. Numerical analysis with different material laws shows the challenges to simulate the ground behaviour realistically. Results of numerical analysis by means of the Finite-Element-Method are presented and the limitation of material laws discussed.
