Design and analysis of a high-rise building located in two different seismic zones utilizing Istanbul seismic Design Code for Tall Buildings (ISDCTB)

The buildings are exposed to dynamic loads which are caused mainly and commonly by both wind and earthquakes and this study will be focused on the seismic design due to the huge earthquake effects which have been known as one of the major problems that threaten the life of people in vast areas around the world. The aim of the thesis is covering the topic of design and analysis a high-rise RC building depending on basic motivations and challenges summarized as the increase of the tendency towards the construction of high-rise buildings around the world, to improve the author's abilities in the analysis and design of this kind of structures due to the lack of experience in this field specially in Iraq as well as checking the capability of the draft version of Istanbul Seismic Design Code for Tall Buildings (ISDCTB-2008) in evaluating the seismic performance by employing its requirements not only for Istanbul but also for site with less effects of seismicity which has been already taken into account in preparing the new draft version of Turkish Earthquake Code-2016 by adding a new chapter for ''Tall Structures''. The thesis is composed of five chapters, each of them dealing with different aspects of the study. Chapter one is an introduction to general issues related to the earthquake effects and explains the purpose of the thesis in addition to the review of the previous literature. Chapter two presents some general issues regarding the tall buildings and defines the performance-based design procedure, which is utilized in design and analysis the case study as well as explains the main guidelines for tall buildings in Iraq and Istanbul. Chapter three examines the methodology of the analysis including the analytical techniques, the nonlinear modeling of RC components, the ground motion selection and the summary of the seismic design stages and their acceptance criteria. Chapter four describes the case study and the results and chapter five summarized the conclusion of the study. The performance-based design procedure is developed by Pacific Earthquake Engineering Research Center (PEER 2010/5) and explained in ISDCTB-2008 as four design stages including two basic analysis types for designing and verification; linear response spectrum and nonlinear time history analysis. These stages have been followed in analysing the case study building and the results showed that the case study has an adequate structural system to be built in two different seismic zones.
