A Structural Design Comparison Between Two Reinforced Concrete Regular 6-Level Buildings using Soil-Structure Interaction in Linear Range

Structural engineers commonly design superstructures as fixed at the base and transmit reactions to infrastructure in order foundation system estimate displacement of soil while disregarding change seismic response that this induces. In article, was transformed into equivalent springs, linear range compared quantified, obtaining results such increased periods, amounts steel reinforcement beams (between 7% 25%) columns 29% 39%), an increase number stirrups per meter 3% 11% between 5% 45% beams) drifts 1% 14%), a decrease basal shear (up 20%), which directly affects structure. This study concludes inclusion soil-structure interaction is necessary for structural range.
