Seismic Design of Mid-Rise Reinforced Concrete Structures According to TEC 2007 and TBEC 2018

Abstract

Reinforced concrete (RC) structure are widely used structural system in buildings across the Turkey. The new Turkish standard on earthquake, TBEC 2018: Turkish Building Earthquake Code, was published on 2018 which is replaced for the old earthquake code, TEC 2007: Turkish Earthquake Code-2007. This paper aims to present a comparison between the seismic design provisions of these two codes for the design of mid-rise RC structures. The code provisions in both codes are evaluated and differences in terms of ductility and strength for the design of mid-rise RC structures are highlighted and presented. It was shown that the design base shear is higher when using TBEC 2018 code. A 4-story building is designed according to both codes and then the performance of the structure was evaluated. Due to differences on allowable drift limit, the R and Cd factors, the structure showed different behaviour when design according to both codes which are discussed in detail in this paper. A cost analysis was also carried out and compared for both buildings.
