Özet

Due to the abundance and severity of earthquakes, there is an urgent need to study the seismic analysis and design of buildings. In this thesis, a structural analysis was conducted to determine the optimum ratio of shear wall areas in a reinforced concrete building. For this purpose, a total of 20 models were generated with varying building and wall dimensions. Twenty and thirty story buildings were selected to understand the effect of varying building heights on their structural behavior. A parametric study on shear wall areas was conducted using different shear wall area to floor area ratios. Building models, therefore, included no wall and some walls with 0.5%, 1% and 1.5% area ratios applied in both x and y directions. Each of these models were subjected to response spectrum analysis using the forces generated according to 2019 dated Turkish Earthquake Code (TEC 19) and 2016 dated American Building Code (ASCE 7-16). The buildings were assumed to be all office buildings located in a severe seismic zone, Avcilar, Istanbul. The thirty story building due to its total height had to be considered tall as per the requirements in TEC 19. The additional requirements were also included in the analysis to understand the impact of tall buildings on optimum shear wall determination. The following parameters were investigated for the optimum shear wall area to floor area ratio: (a) building periods, (b) base shear and shear force resisted by all shear walls, and (c) deflection and story drifts. The results indicated that the ratio of shear wall equal to 1.5% produces the optimum solution.
