The effect of beam-column connections and soil on the seismic behavior of intermediate steel moment-resisting frames

Soil-structure interaction expresses the difference of structural responses between the actual and theoretical rigid based conditions, and depends on the stiffness, mass and damping of soil and structure systems. Nowadays, moment-resisting frame is one the most applicated structural systems. Ductili...
