Abstract

The paper presents the mathematical model to find the response of a structure equipped with viscous fluid dampers (VFD) considering its P-Delta effect and soil-structure interaction (SSI). This model considers dynamic-response reduction in internal forces of beam-columns when the structure is subjected to earthquake excitation. Numerical examples show results of dynamic response of two steel buildings, VFD structures with SSI and without SSI. Some conclusions about the differences between the two structures are drawn to aid civil-engineering structural designers in resisting seismic loading.
