Abstract

There are many structural factors that affect the earthquake performance of buildings. Heavy overhang is the one of these factors which made to increase the storey area on the storeys above the ground storey. Within the scope of this study, the effect of different heavy overhangs on the earthquake performance of the building was investigated, which are commonly used in reinforced-concrete (RC) structures. A sample RC building with no heavy overhangs was chosen as the reference building model for numerical analysis. The numerical analyses were carried out for a total of 16 structural models designed by adding heavy overhangs of different lengths and to different facades of the reference building model. The obtained results were compared with the results of the reference structure model without heavy overhang to reveal the heavy overhang effect. The period, base shear force, displacement and performance levels were obtained for each structural model. It has been determined that the base shear force, period and total mass increase with the increase of heavy overhangs, while the earthquake performance decreases. The obtained results clearly revealed that the earthquake performance was negatively affected with the increase in the amount of closed heavy overhang.
