In addition to high seismicity, poor construction quality, incorrect detailing and structural mistakes in Turkey have caused enormous loss of life and property. Therefore, seismic rehabilitation has been a major topic for civil engineers in Turkey. The object of this research is to develop a simple method that will provide strengthening of buildings without evacuating the inhabitants. This study is based on application of steel-fibre-reinforced mortar on masonry infill walls with the aim of converting nonstructural partition walls into load-carrying walls. The specimens were one-third scale, two-storey, single-bay reinforced concrete frames with hollow brick masonry infills. The main variables were the ratio of fibre (0% and 2%), fibre reinforced mortar thickness (0, 10 and 20 mm), existence of anchorage (non-anchored or anchored) and type of fibres (steel fibre, polypropylene fibre or hybrid fibre). Strengthening by the application of steel-fibre-reinforced mortar on infill walls of frames retarded the early out of plane failure of the walls and converted the existing non-structural walls into load-carrying walls, so that the strength, stiffness and energy dissipation capacity of the frame increased significantly.

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...
Seismic vulnerability, behavior and design of tunnel form building structures Balkaya, C; Kalkan, E (Elsevier BV, 2004-12-01) Multi-story reinforced concrete tunnel form buildings are one of the common structural types in regions prone to high seismic risk due to the buildings inherent earthquake resistance and ease of construction. Despite their good performance during earthquakes in 1999 in Turkey, and abundance of such structures scattered worldwide, current seismic codes and design provisions provide insufficient guidelines for their seismic design. As a compensatory measure, a series of modal and nonlinear static analyses are...
Determination of Quality Level in Mass Housing Projects in Turkey KAZAZ, AYNUR; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2005-02-01) In Turkey, achievement of acceptable levels of quality in the construction sector has long been a problem. Great expenditures of time, money, and resources are wasted each year due to inefficient or nonexistent quality levels prevailing in the industry. The situation is even worse in the case of mass housing projects addressing to low and middle income groups. It is the purpose of this paper to identify the type of deviations resulting in rework in mass housing projects, since construction firms can only in...
Seismic performance of multisimple-span bridges retrofitted with link slabs Caner, Alp; Zia, P. (American Society of Civil Engineers (ASCE), 2002-03-01) During earthquakes multisimple-span bridges are vulnerable to span separation at their expansion joints. A common way of preventing unseating of spans is to have cable or rod restrainers that provide connections between adjacent spans. Alternatively, dislocation of the girders can be controlled with a link slab that is the continuous portion of the bridge deck between simple spans. Seismic retrofit with link slab should be more cost-effective than the existing methods when it is performed during redecking o...
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...
