TBDY 2018’e GÖRE TARİHİ SİLLE AK CAMİNİN STATİK ANALİZİ

TBDY 2018’e GÖRE TARİHİ SİLLE AK CAMİNİN STATİK ANALİZİÖzetKültürün önemli bir parçası olan tarihi binaların deprem gibi doğal afetler ve insanoğlunun yıpratıcı etkilerine karşı korumak ve gelecek nesillere aktarmak çok önemlidir. Bu tür yapıları korumak için tarihi binaların yapısal davranışlarını iyi bilmek gerekir. Tarihi yapıların depreme karşı güvenli olup olmadığını anlamak için yapıların deprem performans analizi yapılmalıdır. Günümüzde sonlu elemanlar yöntemi, tarihi binaların karmaşık geometri sistemlerinin modellenmesinde ve yapısal analizinde yaygın olarak kullanılmaktadır. Çalışmaya örnek teşkil edecek tarihi yapı; Türk İslam Sanatı açısından önemli bir yere sahip olan Konya’daki Sille Ak Cami’dir. 1864 yılında inşa edilip 400 metrekarelik alanı ile Sille’nin en büyük camisidir. Tarihi Sille Ak Caminin TBDY 2018’e göre mevcut durumunun statik hesabı yapılmış ardından SAP 2000 programında yapısal analizi yapılmıştır. Bu çalışmada, yapının taşıyıcı sistemin durumu, kullanılan malzemelerin özellikleri, meydana gelen hasarların değerlendirilmesi, mevcut durumunun tespiti yapılarak gelecek nesillere taşınması, gerekli parametrelerin tartışılarak çözüm önerilerinin ortaya konması amaçlanmaktadır.Anahtar Kelimeler: Tarihi Yığma Yapı, TBDY-2018’e Göre Analizi, Sille Ak CamiiSTATIC ANALYSIS OF HISTORICAL SİLLE AK MOSQUE ACCORDING TO TBDY-2018AbstractIt is very important to protect the historical buildings, which are an important part of the culture, against natural disasters such as earthquakes and the destructive effects of human beings and to pass them on to future generations. To protect such structures, it is necessary to know the structural behavior of historical buildings. Earthquake performance analysis of the structures should be performed to see whether the historical buildings are safe from earthquakes. Today, the finite element method is widely used in the modeling and structural analysis of complex geometry systems of historical buildings. The historical structure that will serve as an example for the study; Sille Ak Mosque in Konya, which has an important place in Turkish Islamic Art. Built in 1864, it is the largest mosque in Sille with an area of 400 square meters. According to TBDY 2018, the structural analysis of SAP 2000 program was performed by manual static calculation according to the current situation of the historical Sille Ak Mosque. In this study, it is aimed that evaluate the condition of the structural system, the properties of the materials used, the evaluation of the damages occurring, the determination of the current state of the structure to transfer the next generations, and the solution of the necessary parameters by discussingKeywords: Historical Masonry Building, Analysis According to TBDY-2018, Sille Ak Mosqu

A New Face of China: Sharp Power Strategy and its Global Effects

China’s rapid emergence as a great power in the world has not only influenced the actions of other countries, but also introduced new concepts to academic discourses. One of these concepts is sharp power, which has entered academia to theoretically explain China and Russia’s rise. More particularly, China’s actions to consolidate its position as a great power and to restore its image, have given rise to this concept. Its influence in other countries is intangible in nature and tools, but it has great tangible effects. At first, this article seeks to examine sharp power as a new concept and explain China’s influential behaviours. Sec-ond, it will study the rationale of China’s sharp power and then scrutinize its indicators in the world. The paper assumes that China has infiltrated the world by using intangible but powerful tools and is consolidating its foothold in different countries

Left Main Coronary Artery Revascularization in Patients with Impaired Renal Function: Percutaneous Coronary Intervention versus Coronary Artery Bypass Grafting

Introduction: The evidence about the optimal revascularization strategy in patients with left main coronary artery (LMCA) disease and impaired renal function is limited. Thus, we aimed to compare the outcomes of LMCA disease revascularization (percutaneous coronary intervention [PCI] vs. coronary artery bypass grafting [CABG]) in patients with and without impaired renal function. Methods: This retrospective cohort study included 2,138 patients recruited from 14 centers between 2015 and 2,019. We compared patients with impaired renal function who had PCI (n= 316) to those who had CABG (n = 121) and compared patients with normal renal function who had PCI (n = 906) to those who had CABG (n = 795). The study outcomes were in-hospital and follow-up major adverse cardiovascular and cerebrovascular events (MACCE). Results: Multivariable logistic regression analysis showed that the risk of in-hospital MACCE was significantly higher in CABG compared to PCI in patients with impaired renal function (odds ratio [OR]: 8.13 [95% CI: 4.19–15.76], p < 0.001) and normal renal function (OR: 2.59 [95% CI: 1.79–3.73]; p < 0.001). There were no differences in follow-up MACCE between CABG and PCI in patients with impaired renal function (HR: 1.14 [95% CI: 0.71–1.81], p = 0.585) and normal renal function (HR: 1.12 [0.90–1.39], p = 0.312). Conclusions: PCI could have an advantage over CABG in revascularization of LMCA disease in patients with impaired renal function regarding in-hospital MACCE. The follow-up MACCE was comparable between PCI and CABG in patients with impaired and normal renal function
