Abstract:

The rough building costs required for adequate strength in reinforced concrete buildings have been investigated by considering different earthquake design classes. Building models, which were determined to represent the existing building stock, were analyzed based on four different base overturning moment ratios in line with the parameters considered. The structural systems of the building models are considered in two groups as framed system and shear walled + framed system, and the effects of shear wall effects on building costs are examined. It is observed that there is no significant increase in the cost of the rough building costs in the case of shear walled + framed structural systems. The rough building costs calculated in the buildings designed in DTS2-DTS3-DTS4 give similar results. However, the cost increase in DTS1 is approximately 10% on average. It is reached the conclusion that, in addition to the serious strength increase advantage to be provided by the choice of shear walled + framed structural systems, the insignificant cost increases that occur can be ignored. For this reason, it is recommended to prefer shear walled + framed structural systems in all earthquake design classes.
