Simulation of soil liquefaction due to earthquake loading

Soil Liquefaction due to Long Duration Earthquakes with Low Acceleration

Severe soil liquefaction due to a long duration earthquake with low acceleration occurred at Tokyo Bay area in the 2011 off the Pacific coast of Tohoku Earthquake. This phenomenon clearly shows that soil liquefaction is affected by properties of input waves. This paper describes effect of wave properties of earthquake on liquefaction using effective stress analysis with some earthquakes. Analyt...

Simulation of Earthquake Liquefaction Response on Parallel Computers

This paper presents a parallel nonlinear finite element program, ParCYCLIC, which is designed for the analysis of cyclic seismically-induced liquefaction problems. Key elements of the computational strategy employed in ParCYCLIC include the deployment of an automatic domain decomposer, the use of the multilevel nested dissection algorithm for the ordering of finite element nodes, and the develo...

Fuel Reserve Tanks Dynamic Analysis Due to Earthquake Loading

In this paper, the dynamic analysis of fuel storage tanks has been studied and some equations are presented for the created fluid waves due to storage tank motions. Also, the equations for finite elements of fluid and structure interactions, and boundary conditions dominant on structure and fluid, were researched. In this paper, a numerical simulation is performed for the dynamic analysis of a ...

Numerical modelling of multi-directional earthquake loading and its effect on sand liquefaction

Earthquakes generate multi-directional ground motions, two components in the horizontal direction and one in the vertical. Nevertheless, the effect of vertical motion on site response analysis has not been the object of extensive research. The 2010/2011 Canterbury sequence of seismic events in New Zealand is a prime example among other earlier field observations strongly corroborating that the ...
