Abstract:

In this study, non-linear analysis is considered under the Evaluation and Design Based on Strain (ŞGDT) criteria specified in the regulation, of a high reinforced concrete structure with a height of 72 m according to the Turkish Building Earthquake Code (TBDY) 2018 under the Earthquake Design Class 1 (DTS) category. Considering the performance and structural behavior of different flooring types, comparisons were made. Within the same vertical support system, 4 different models, commonly used in reinforced concrete structures, consisting of conventional slab system, ribbed hardy slab system, flat slab system and non-modeled floor conventional slab system were considered. The same strength properties are included in the material selection of the concrete and reinforcement used for each building system. Inelastic strains obtained from the analyses were compared with each other and performance levels were determined according to different flooring types. As a result, in non-linear behavior analysis, it has been observed that modeling of slabs can change the element damage levels and building behavior, contributing to the horizontal in-plane rigidity of the building systems and causing more strain on the vertical elements.
