Nonlinear Static Seismic Analysis and Its Application to Shallow Founded Buildings with Soil-Structure Interaction

This paper presents new research in the field of nonlinear static seismic analysis and N2 method for soil-structure systems. The rationale this study stems from inclusion systems simplified displacement-based design methods. conducted comprises three parts, including original experimental investigations, development numerical models validation results. A methodology is presented that provides a step-by-step procedure implementation on Results dynamic shake-table test scaled structural model founded compacted dry sand are presented, experiment developed calibrated with interaction effects. indicates one main significance paper, which variation between analytical how they can be compared. Lastly, case was 3D steel building. building analysed using pushover fixed base-case by considering results both observed cases were mutually compared further examined validating them analyses. comparison inter-story drifts, calculated according to time-history show good agreement when used buildings compliant soils. Overall, it decrease drifts appears at ground level also framework future field, instance, different types buildings, typologies irregularities system.
