On the finite element modeling of a particular shallow foundation system for soft soil
Soelarso Soelarso, Eduard Antaluca, Jean-Louis Batoz and Fabien Lamarque

 
Abstract
    The presentation deals with an investigation on the static and dynamic behavior of a five floors reinforced concrete building supported by a shallow foundation system, called SNSF (Spider Net System Footing). The present study concentrates on the linear static under permanent and life vertical loads and on the free vibrations of the upper structure and the foundations. The study based on performing 3D solid finite elements includes the soil underneath (one layer of 2 m and an additional layer of 9 m). Several aspects are investigated like: the structural analysis of the SNSF foundation compared to a simpler raft foundation and the soil-foundation interaction of the soil and the structurefoundation system on the first frequencies and modes of vibration.
