Yüksek Katlı Betonarme Binaların Türkiye Deprem Yönetmeliğine Göre Tasarımı

Abstract

The new Turkish earthquake code (TEC 19) is primarily based on Performance Based Seismic Design, and includes elements from the “Guidelines for Performance-Based Seismic Design of Tall Buildings,” a code published by the Pacific Earthquake Engineering Research Center in the United States. This article studies the advantages and disadvantages of TEC 19 with respect to the preexisting code (TEC 07), and the impact of the new code on the design of high rise buildings. In order to understand the effects of the new code, two 30 story residential buildings—one constructed using tunnel formwork, and the other with special moment resisting frames—were designed according to TEC 19 and TEC 07. The design results of the earthquake analyses were used to understand the impact of TEC 19 on high rise buildings, since these buildings with similar framing systems are now commonly being built in most of the major cities of Turkey. The analyses also included the total base shear, axial forces, shear forces, and bending moments of some structural members. Based on the design results, it was observed that the new code generally generated higher earthquake forces on both buildings with tunnel formwork and special moment framing system.
