Simplified Numerical Analysis of Soil–Structure Systems Subjected to Monotonically Increasing Lateral Load

Numerical modelling of the soil in seismic design structures is always a daunting task. The goal this article to develop simplistic numerical technique for shallow founded buildings on compliant soils. An existing large-scale experimental research (TRISEE) was used calibration. physical model comprised rigid square foundation placed sand bed connected column and subjected dynamic sine loading. results from TRISEE experiment are well known commonly by researchers field, yet none studies were conducted considering loose case. Nonlinear link elements linear springs representing soil. It determined that behavior highly influenced stiffness, selected hysteresis model, p-y curve. Considering software limitations, models represent good manner. Based obtained experiment, case study steel frame building with SSI effects included conducted. research, authors recommend implementation into building’s phase since they exhibit unfavorable impacts can lead underdesigned structural elements. However, it has be emphasized certain limitations exist due simplified approaches research.
