Analysis of the behavior of piles, pile groups, rafts and piled rafts subjected to both lateral and vertical loadings as well as moments has been particular interest in geotechnical engineering. However, the behavior of rafts and piled rafts with 3D shear wall-frame structure subjected to horizontal and vertical loading has not received as much attention. In this paper, a new version of computer program ASTN3 was developed in order to examine the behavior of piled raft with 3D-superstructure of shear walls supported by non-identical piles. Shear walls were used here to resist lateral loads from a side and from another side to control lateral displacements of top floors. Full interaction between raft, piles and the soil, was considered in the software based on both Framework analogy and composed coefficient technique. Results of ASTN3 were verified by comparing to published results. Herein, a parametric study of 3D-space structures-shear walls with piled raft on Port-Said soil medium exposed to seismic loads beside gravity loads were analyzed by ASTN3. Discussion for the numerical results is performed and conclusions were drawn.
