Interstory Drift Evaluation of High Ductile Concentrically Steel Brace and Moment Transmitting Steel Frame
Abstract
Earthquakes have always been a great danger for humanity. There have been and continue to be important developments throughout human history to minimize the impact of this great danger. Turkey is located in a geologically active region and is home to numerous fault lines, including three major ones. Consequently, it can be said that it is an important experimental center in the studies to be carried out to be minimally affected by earthquakes. Steel structures, which are more advantageous against earthquakes, can be designed with many different systems. In this study, selected a plot of land in the provincial center of Düzce, one of the cities located in the 1st degree risk zones in Turkey for examine the effects of design differences under horizontal and vertical loads. The moment transmitting frame and the centrally braced frame have been designed between the same axes in the same building design. This study was examined for 5 different two-dimensional models with brace and moment transmitting systems. Interstory drift analyses will be performed by comparing the reduced spectra according to the type of building structural system defined in the Turkey Building Earthquake Code (TBEC 2019) with the 1999 Düzce Earthquake Spectrum. Interstory drift analysis of all designs were completed and their advantages and disadvantages comparative were evaluated.
