Seismic performance assessment of existing buildings requires the existing material's properties to be determined as this has a significant influence on the seismic risk. As one of the most common construction type in Turkey, masonry buildings are assessed generally based on the recommended material properties specified in relevant codes as opposed to testing of samples taken from the existing buildings. However, due to different material types and workmanship quality, the specified properties might be quite different from the existing values. For these reasons, a comprehensive study has been undertaken to investigate the influence of mechanical properties of existing masonry buildings on their seismic performance. The study has two parts. First, the mechanical properties of materials commonly used in the Turkish masonry construction were determined by extracting wallets from existing structures and conducting laboratory experiments. The second part of the study was devoted to seismic performance assessment of selected buildings using material properties determined based on field tests and values specified in the codes. Within the context of determining existing mechanical properties, compression, diagonal tension, and shear tests were conducted on the specimens taken from existing buildings. Stress-strain responses for compression and diagonal tension tests were measured. When compared with the allowable strength values recommended by the current Turkish design code, the test results indicated significant differences from code recommended values. Thus, building assessment results were found to be greatly influenced by the material strength estimations. Based on the evaluation of material test results, lower-bound material properties are proposed for use in assessment of masonry buildings.

Probabilistic assessment of earthquake insurance rates for important structures: Application to Gumusova-Gerede motorway Yücemen, Mehmet Semih; ERDİK, MUSTAFA ÖZDER (Elsevier BV, 2008-01-01) A probabilistic model is presented for the assessment of the earthquake insurance rates for important engineering structures, for which the seismic losses could be quite significant. The proposed model is used to estimate the earthquake insurance premiums for the structures taking place in the Bolu Mountain Crossing in the Gumusova-Gerede motorway Section, Turkey. The model requires two types of studies, namely: seismic hazard analysis and estimation of potential damage to structures based on damage probabi...
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...
Analytical Investigation of Lateral Strength of Masonry Infilled RC Frames Retrofitted with CFRP Erdem, Ibrahim; Akyüz, Uğurhan (American Society of Civil Engineers (ASCE), 2010-07-01) In this study, two reinforced concrete frames with hollow clay tile masonry infill walls, retrofitted with diagonally applied carbon fiber-reinforced polymer (CFRP), which were tested previously, were analytically investigated. A simple material model for the masonry infill wall strengthened with CFRP is suggested. The lateral strength of each rehabilitated frame was obtained by pushover analysis of four different models using a commercially available finite-element program, and the results were compared wi...
Seismic design of lifeline bridge using hybrid seismic isolation Dicleli, Murat (American Society of Civil Engineers (ASCE), 2002-03-01) This paper presents the merits of a hybrid seismic isolation system used for the seismic design of a major bridge. The bridge is analyzed for two different arrangements of seismic isolation systems. The first arrangement consists of friction pendulum bearings at all substructure locations; the other incorporates a hybrid system where laminated elastomeric bearings are used at the abutments and friction pendulum bearings at the piers. Analysis results have demonstrated that the hybrid seismic isolation syste...
Seismic behavior of autoclaved aerated concrete low rise buildings with reinforced wall panels Gökmen, Furkan; Binici, Barış; Canbay, Erdem (Springer Science and Business Media LLC, 2019-07-01) Reinforced Autoclaved Aerated Concrete (AAC) wall panels are more commonly used to construct load-bearing walls in low-rise prefabricated buildings located in seismic zones. In the scope of this study, the seismic response of buildings constructed with reinforced AAC wall panels was investigated. To this end, an in situ test was conducted on a two-story test building under reversed cyclic displacement excursions. It was determined that the test building could carry a lateral load of 60% more than its weight...
