Fragility functions are determined for low- and mid-rise ordinary concrete buildings. A hybrid approach is employed where building capacities are obtained from field data and their dynamic responses are calculated by response history analysis. Lateral stiffness, strength and deformation capacities of the sample buildings are determined by pushover analyses. Uncertainties in lateral stiffness, strength and damage limit states are expressed by using statistical distributions. The seismic deformation demands of the subject buildings are calculated under 82 ground motions. Peak ground velocity is selected as the measure of seismic intensity since it has been observed that maximum inelastic displacements are better correlated with PGV. The results have revealed that the type of investigated buildings is highly Vulnerable to strong ground shaking expected during the future earthquakes. Moreover, their fragility increases with the number of stories.

Influence of the shear wall area to floor area ratio on the seismic performance of existing reinforced concrete buildings Günel, Ahmet Orhun; Burak Bakır, Burcu; Department of Civil Engineering (2013) An analytical study is performed to evaluate the influence of shear wall area to floor area ratio on the behavior of existing mid-rise reinforced concrete buildings under earthquake loading. The seismic performance of five existing school buildings with shear wall ratios between 0.00% and 2.50% in both longitudinal and transverse directions and their strengthened counterparts are evaluated. Based on the structural properties of the existing buildings, additional buildings with varying shear wall ratios are ...
HYSTERETIC RESPONSE OF REINFORCED-CONCRETE INFILLED FRAMES ALTIN, S; ERSOY, U; TANKUT, T (1992-08-01) Strengthening of framed reinforced concrete structures by cast-in-place reinforced concrete infills is commonly used in practice. The objective of this study is to investigate the behavior of such infilled frames under seismic loads. For this purpose, 14 two-story, one-bay infilled frames are tested under reversed cyclic loading simulating seismic action. The variables investigated are thc effect of type of infill reinforcement, thc connection between the frame and thc infill, and the flexural capacity of c...
Assessment of seismic fragility curves for low- and mid-rise reinforced concrete frame buildings using Duzce field database Erberik, Murat Altuğ (2005-06-01) This paper focuses on the generation of fragility curves for low-rise and mid-rise reinforced concrete frame buildings, which constitute approximately 75% of the total building stock in Turkey and which are generally occupied for residential purposes. These buildings, which suffered extensive damage after recent earthquakes, are not designed according to the current code regulations and the supervision in the construction phase is not adequate. Hence the buildings possess many deficiencies like irregulariti...
Modelling of strengthened hollow brick infills BARAN, MEHMET; Ozcelik, Ramazan; Sevil, Tugce; Canbay, Erdem (2013-02-01) Strengthening the existing hollow brick infill walls by bonding high-strength precast concrete panels or applying steel fibre reinforced mortar was found to be an occupant-friendly seismic retrofitting technique for the buildings in use with deficient reinforced concrete structural systems. Both techniques convert the existing non-structural hollow brick infill walls into load-carrying structural members. To verify the effectiveness of the techniques, 20 reinforced concrete frames with hollow brick infill w...
Fragility analysis of wide-beam infill-joist block RC frames Donmez, Cemalettin; Karaarslan, Enes; Erberik, Murat Altuğ (2022-01-01) Purpose: The purpose of the presented study is to develop fragility curves for the wide-beam infill-joist block reinforced concrete structures. Theory and Methods: Nonlinear time history analyses are performed for the set of selected ground motions. The performance levels are identified through pushover analysis and fragility curves are produced for ground motion parameters. Results: Fragility curves obtained for the wide-beam RC frames presents a different characteristic than the curves obtained for the co...
