Abstract
The work is related to the Ph.D. subject of the first author on the analysis and design of shallow foundation systems in the context of earthquake resistant constructions in Indonesia. We focus here on a particular system called SNSF (Spider Net System Footing) that has been proposed and successfully used for around 10 years. This paper deals with the analysis of a unit cell of SNSF consisting of an assemblage of concrete vertical ribs and horizontal plate subjected to a central loading. We propose a geometrical 3D model and analyses based on 3D solid and shell elements for a detailed static analysis of the structure under central load or under self-weight. We also report some results considering the soil structure interaction, assuming linear elastic properties of the soil
