Design of seismically isolated hospital structures have become popular in Turkey within last five years especially after Ministry of Health’s policy change. The new hospital complexes of about twenty campuses has been either under design or scheduled for planning for the next five years. The Ministry strictly requires use of seismic isolation systems for high risk seismic regions not only to mitigate the adverse effect of earthquakes on structures but also to keep operating expensive medical devices just immediately after the earthquake. Since the technology has been very new to Turkish market, a flux of manufacturers promoting different products were inevitable that have created some richness of education that also sometimes ended up in confusions. Therefore, the selection of seismic isolation systems for different geometries of structures over different soil conditions have become a hurdle for the engineers who has started learning this new technology. In this study, seismic isolation systems used at some of the hospital designs have been compared in terms of types, sizes, mechanical properties, expected performances. The case study includes five hospitals in which two of the complexes have almost been completed and three of them are still under construction. In many cases, friction pendulum based systems and lead rubber bearings have been selected based on the detailed analytical studies. It shall also be noted that two of the hospitals are very close to an active fault that required a comprehensive study of near fault effects in seismic hazard computations.

A Critical Analysis of Urban Regeneration Projects in Turkey Displacement of Romani Settlement Case Cin, Mehmet Melih (2016-01-01) This paper looks into urban regeneration practices targeting Roma people who generally live in city centers' valuable areas in Turkey. First it analyzes Sulukule urban regeneration project through the conceptual framework of housing rights. Then, drawing from the experiences of Sulukule, it focuses on Ege neighborhood urban regeneration project, which will also be applied in a Roma settlement. The data for Ege neighborhood draws from the questionnaires and the interviews conducted with 102 people in the reg...
The Effect of Defects Created in Microporous Vanadosilicate AM-6 Thin Films in Photocatalysis Kuzyaka, Duygu; Akata Kurç, Burcu (2018-11-30) Micro and Nanotechnology Department, Middle East Technical University, Ankara, , Turkey The development of visible-light effective photocatalysts allows low cost degradation of toxic non-biodegradable organic pollutants. Vanadium, present in a specific oxidation state within the structure of SiO2 matrix could open up the gateway to investigate and tailor the defects created for such photocatalytic applications. Vanadosilicate AM-6, which is a large pore microporous material containing semiconducting monatom...
A Case study on how public primary schools promote health Çetintürk, Arzu; Akar, Hanife; Department of Social Policy (2013) The main drive of this study is to investigate how urban public primary schools promote health in Turkey with a qualitative study conducted in a middle-sized urban school, in Ankara. The current health promotion practices in Turkish urban public primary schools were examined through a case study utilizing semi-structured interviews conducted with 9 classroom teachers, 2 school administrators, 2 parents that are parent-teacher association members and 2 canteen operators. In addition, a classroom activity was...
The Financial and Operating Performance of Privatized Companies in the Turkish Cement Industry MÜSLÜMOV, Alövsat (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2005-6) This paper examines the post-privatization performance of privatized companies in the Turkish cement industry. The findings indicate that, when performance criteria for both the state and private enterprises are considered, privatization in the cement industry results in significant performance deterioration. Total value added and the return on investment declines significantly after privatization. This decrease mainly stems from deterioration in asset productivity. The decline in asset productivity, howeve...
A comparative study of the thermal performance of building materials Elias Özkan, Soofia Tahira; Surmeli, Nesen; Yannas, Simos (2006-12-01) This study focuses on the environmental performance of a selection of buildings in the typical Central Anatolian village of Şahmuratli in Turkey. The objective was to search for affordable and energy-efficient construction techniques suitable for rural settlements and incorporating traditional cultural values in a semi-arid upland region characterised by long severe winters and hot, dry summers. This was pursued by analysing temperature and humidity measurements within buildings constructed from a variety o...
