TAILIEUCHUNG - Performance assessment of steel isolated structures considering heating in lead core based on seismic risk

This paper presents a methodology to utilize performance-based seismic design procedure for evaluating the effect of heating in lead core of isolated structures with lead-rubber bearing based on collapse assessment and seismic loss estimation. Nonlinear archetypes of conventional 4-story steel special moment resisting frame, isolated intermediate moment resisting frame with and without heating in lead core effect are compared with each other under far-field (FF) and near-field earthquakes. | JSEE Vol. 18, No. 4, 2016 Performance Assessment of Steel Isolated Structures Considering Heating in Lead Core Based on Seismic Risk Majid Gholhaki1*, Mehdi Banazadeh 2, and Hossein Parvini Sani 3 1.

Nonlinear archetypes of conventional 4-story steel special moment resisting frame, isolated intermediate moment resisting frame with and without heating in lead core effect are compared with each other under far-field (FF) and near-field (NF) earthquakes. The results of this study show that heating in lead core increases collapse risk, expected annual loss (EAL) and expected annual fatalities up to 40%. Besides, it has been found that the effect of heating in lead core for isolated structures increases under NF comparing with FF ground motions. Sensitivity analysis is employed to study the effect of modeling uncertainty on the loss estimation process show that the effect of modeling uncertainty on the EAL increases for NF ground motions comparing with FF ground motions. 1.
