An analysis according to regulation of TDY 2007 and TBDY 2018 by equivalent earthquake load method of a reinforced concrete building

Turkey is located at high risk seismic region. As a result of earthquakes happened in our country, loss of life and property was encountered. The increment in the amount in this loss, enforced us to give more importance to the design of seismic resistant buildings. For this reason seismic standarts and design codes were prepared. These standarts are revised depending to technological development and increment in seismic know-how during time. The last seismic code; Turkish Building Seismic Code 2018; was published in official gazette at 18 March 2018 and come into force at 01 January 2019. The decrease in loss of life and property based upon earthquakes, might be possible by understanding and practicing these codes in the bestway. In this study; the differences and similarities between 2007 and 2018 Turkish Seismic Codes were compared. In the first part of the study seismic damages were investigated, afterwards the 2007-2018 codes were compared according to Equivalent Lateral Earthquake Load method and numerical comparisons were made on selected analysis building models. In accordance with this purpose a sample analysis building model having framed and wall-framed structural system with / without basement were selected at two locations (Konya and İstanbul) and at two soil classes ( Z1-ZA and Z3-ZD) and analysed. The analysis results were compared. As a result, TBDY 2018 concluded an increase in floor displacements and a decrease in floor shearing forces.
