Investigation on the Ability of Intensity Measures for Reliable Seismic Collapse Assessment of Steel Smrfs With Linear Viscous Dampers

Abstract eng:
Nowadays, passive energy dissipation systems are used in the seismic design of new structures and retrofit of existing structures. Fluid viscous dampers are categorized as one of the important types of passive energy dissipation systems, which convert the kinetic energy caused by seismic excitation to heat. Using viscous dampers can considerably decrease the seismic response of structures. In this paper, seismic collapse behavior of steel Special Moment Resisting Frames (SMRFs) equipped with Fluid Viscous Dampers (FVDs) is investigated. Incremental Dynamic Analysis (IDA) is applied to obtain the collapse capacity values for three low- to mid-rise steel SMRFs equipped with FVDs considering different ground motion Intensity Measures (IMs). After obtaining the collapse capacity, IM col , values by using different IMs, the ability of the considered IMs to reliably predict the seismic collapse capacity of these structures is investigated. For this purpose, the efficiency and sufficiency of the IMs, as the main desirable features of an optimal IM for collapse capacity prediction, are considered to classify the IMs.
