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. 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. In this article, a method is introduced for external strengthening of typical reinforced concrete buildings that represent the majority of the built environment in Turkey. The method suggests addition of shear walls, which are connected to each other by means of reinforced concrete diaphragms on two separate floor levels and to the existing external columns and floor system at corners of the building. The advantage of shear walls in seismic performance is already known; however, this article discusses the feasibility of the proposed method in terms of architectural viewpoint, since the method unavoidably covers great modifications on the architectural form of the building. As a whole, this external strengthening method provides a typical facade resemblance by means of additional structural members without emptying the building.

Cost effect of earthquake region and soil type for office buildings in Turkey Kanit, Recep; Gunduz, Murat; Ozkan, Omer (Elsevier BV, 2007-10-01) In this study, the change in the load-bearing system cost of a reinforced concrete office building has been investigated in relation to the earthquake regions and soil types. Three different office projects each with five stories were investigated. The structural design calculations have been made according to four different soil types and four different earthquake regions. According to each combination, concrete, steel and formwork adopted approximations were calculated to reach the rough cost of each offi...
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 ...
Performance-based seismic rehabilitation of damaged reinforced concrete buildings Sucuoğlu, Haluk; Gunay, MS (American Society of Civil Engineers (ASCE), 2004-10-01) A building stock consisting of 130 medium-rise reinforced concrete buildings were damaged moderately during the recent earthquakes in Turkey. These buildings were rehabilitated by using simple, cost-effective methods where the newly added shear walls comprised the primary lateral load resisting system. In the presented study, different seismic performance evaluation procedures are tested first on the samples of damaged buildings for predicting their observed performances. Then the expected performances of t...
Re-examination of damage distribution in Adapazari: Geotechnical considerations Bakır, Bahadır Sadık; Yakut, Ahmet (Elsevier BV, 2005-06-01) The role of ground conditions in damage distribution patterns of buildings in the city of Adapazari during the 17 August 1999 Izmit (Kocaeli) earthquake (M-w 7.4) is investigated. Damage was concentrated in the central districts of the city over the alluvial basin where four to seven-story reinforced concrete buildings were most adversely affected. Two distinct and mutually exclusive modes of building damage were observed on the alluvium: structural system failures due to strong ground shaking, and foundati...
Strengthening of reinforced concrete frames by custom shaped high strength concrete masonry blocks Arslan, Güray; Polat, Mustafa Uğur; Department of Civil Engineering (2009) Located on one of the highly active seismic fault systems in the world, the building stock in Turkey is mainly composed of reinforced concrete frames with 4-5 stories. Due to design and construction deficiencies resulting from the use of unqualified personnel and insufficient supervision, many of these buildings lack lateral stiffness, ductility and strength. For many structures, there is a need to alleviate these deficiencies by means of some rehabilitation techniques prior to earthquakes. One approach als...
