ANALYSIS AND RETROFITTING OF BUILDING STRUCTURES FOR POUNDING FORCES

taqweem begum shakil qureshi, Arshad Hashmi

Abstract


Learned from recent and past Earthquake, post earthquake damages sustain structural and non-structural damage in the building even collapse of structures. This may cause the building non-functional after the earthquake, which may be problematic in some structures, like hospitals, which need to remain functional even after the earthquake. Among the all possible damages pounding is commonly observed in several earthquakes. A parametric study carried by taking two adjacent buildings G+13(45.1m) and G+8 (24.1m) for pounding forces. Two different ground motion data for input Chamoli, Elcentro Considered. The effect of pounding force is studied using nonlinear time histories in ETABS Software. Gap element is connected to calculate the pounding force between buildings. Pounding Force can be reduced effectively when separation gap provided is sufficient but Due to high land cost in dense populated areas these structures are constructed very close to each other. When two buildings are too close to each other they may Collides, which leads to pounding during strong ground motion .so it’s required to protect buildings by using special tools. For that small building is considered stiff and taller building retrofitted with fluid viscous damper to reduced pounding forces significantly. This paper deals with the analysis of pounding behavior of adjacent buildings retrofitted with fluid viscous damper. Comparative Study for different model is carried out in terms of Pounding force (impact force), displacement, number of impact, Effect fluid viscous damper to reduce global damping with or without retrofitting.

Keywords:  seismic pounding, Retrofitting, Nonlinear time History, Seismic analysis.
