As an earthquake prone country, in Turkey Seismic Base Isolation applications increase tremendously. The main reason of this increase is the memorandum released by Ministry of Health by which application of Seismic Base Isolation becomes obligatory for the Hospitals with a bed capacity higher than 100. After the initiation of using seismic isolators on the hospitals, the subject becomes more known and usage of seismic isolations extend to data centres and other communication buildings. Beside the seismic base isolation application, in the new draft Turkish Earthquake Code which is released in 2017 a chapter is devoted to seismic base isolation. Among the two isolation systems typically used in Turkey, Friction Pendulum Systems (FPS) with double sliding surfaces are more common. There are some Lead Rubber Bearing (LRB) systems as well. So far, there are some seismically isolated hospitals which are operating, among which one was subjected to two earthquakes in 2017 with magnitudes 5.3 and 6.2. These earthquakes did not affect the hospital at all. Unfortunately, there weren't any monitoring systems installed. The hospital which was subjected to the earthquakes is isolated by LRB system. In one of the Hospital Buildings which becomes operational, seismic base isolation alone was not enough to satisfy the conditions stated by the memorandum of Ministry of Health so a bracing system was used to decrease the floor accelerations. In this study, the details of five hospital buildings which are seismically isolated by using FPS or LRB are discussed. So far in one of them a monitoring system has been installed. © NCEE 2018.All rights reserved.

Suggestions

Developing an innovative architectural and structural solution for seismic strengthening of reinforced concrete residential buildings
Toker, Saadet; Ünay, Ali İhsan; Department of Architecture (2004)
The recent earthquakes in Turkey have shown the poor seismic performance of reinforced concrete. This led to widespread utilization of several strengthening methods, each of which is convenient in different aspects. However, what is required to apply any of these methods is to evacuate the building in question since the interruptions are mostly within the building and to the structural members. This study proposes a method for external strengthening of typical five storey reinforced concrete buildings that ...
Displacement-based fragility functions for low- and mid-rise ordinary concrete buildings
Akkar, S; Sucuoğlu, Haluk; Yakut, Ahmet (SAGE Publications, 2005-11-01)
Fragility functions are determined for low- and mid-rise ordinary concrete buildings, which constitute the most vulnerable construction type in Turkey as well as several other countries prone to earthquakes. A hybrid approach is employed where building capacities are obtained from field data and their dynamic responses are calculated by response history analyses. Field data consists of 32 sample buildings representing the general characteristics of two-to five-story substandard reinforced concrete buildings...
Low cycle fatigue effects in the damage caused by the Marmara earthquake of August 17, 1999
Acar, Fikri; Gülkan, Polat; Department of Civil Engineering (2005)
This study mainly addresses the problem of estimating the prior earthquake damage on the response of reinforced concrete structures to future earthquakes. The motivation has arisen from the heavy damages or collapses that occurred in many reinforced concrete structures following two major earthquakes that recently occurred in the Marmara Region, Turkey. The analysis tool employed for this purpose is the package named IDARC2D. Deterioration parameters of IDARC's hysteretic model have been calibrated using a ...
Re-characterization of architectural style of reinforced concrete building facades by exterior seismic strengthening
Toker, Saadet; Ünay, Ali İhsan (Elsevier BV, 2006-12-01)
Recent earthquakes in Turkey have shown the poor seismic performance of reinforced concrete residential buildings. This led to widespread utilization of several strengthening methods, each of which is convenient in different aspects.

Cost-benefit analysis for various rehabilitation strategies
Çetinceli, Serkan; Yakut, Ahmet; Department of Civil Engineering (2005)
Over the last decade, six major earthquakes that occurred in Turkey dramatically demonstrated the poor performance of the buildings that were designed and constructed far from Turkish seismic code̕s requirements. The Marmara region, where most of the population and industry is located, is in the active seismic zone. With the rising cost of damages due to earthquakes, the necessity of the cost-benefit analysis for various rehabilitation strategies used in existing buildings has become a major concern for the...
