Liquefaction is a phenomena in which when loose, cohesion less, saturated soils in undrained condition when subjected to earthquake loading or dynamic loads behave like a fluid due to subsequent loss of shear strength and increase in pore water pressure. The effect of liquefaction can be predicted in three stage: Evaluation of Susceptibility, hazard and deformations. Currently, a tool has been developed for the assessment of liquefaction hazard. Many different methods are available for the assessment of liquefaction hazard but the stress based approach has been chosen for the development of the tool.
SDMWT is a computing tool designed as Graphical user Interface on the base of C language which serves as a computer application. This application is used for the "Seismic Design of Monopile for Offshore Wind Turbines". Considering Geo technical data along with met-ocean and Turbine data dimensions of a monopile are designed under seismic, lateral and gravity loading conditions for site specific environment. Outstanding part of the application is that it generates a 3D animated view of a monopile that gives stress distribution generated on the basis of Finite element modelling.
