Tekin, Muhammed; Gürbüz, Ali
In this study, the fragility curves were formed for 1 and 2 stories reinforced concrete (RC) residential buildings. The information regarding the structures was taken from projects of the buildings. Nonlinear pushover (NP) analyze was performed to 84 RC buildings which were divided to 2 groups. The buildings built 1998 and later were called Group-A. The building built before 1998 was called Group B. As for nonlinear analysis, a 3D computer model was drawn for each building and nonlinear analyses were applied to these models. Each building was analyzed for 2 dimensions (X and Y). Totally 168 NP analysis were performed for each building. 4 damage limits (slight, moderate, heavy and complete) and 5 damage zones (undamaged, slight, medium, extensive and collapse) were determined according to maximum interstory drift ratio. Fragility curve parameters were obtained at the result of the NP analysis. Probability density functions were calculated with the help of lognormal mean and lognormal standard deviation values of limit states. The fragility curves were generalized for the buildings in Group A and Group B. At the conclusion of this work; 8 fragility curves obtained for 1 and 2 stories reinforced concrete buildings in. Using these 8 curves; damage possibility can be estimated for RC buildings which have same features.

Soğukpınar, Hacı; Bozkurt, İsmail
In this paper, aerodynamic performance of airplane NACA 2415 airfoils were numerically investigated to understand effect of angle of attack on the aerodynamic performance. The lift and drag coefficient, lift to drag ratio and power coefficients around NACA 2415 aerofoil were calculated with SST turbulence model and are compared with two different experimental data to validate simulation accuracy of Computational Fluid Dynamics approach. Result indicates that at the low angle of attack, the lift coefficient of NACA 2415 aerofoil obtained in the present study is in a good agreement with experimental results but after zero degree agreement is not good with experimental results.

Kaptan, Kubilay
The paper presents strengthening solutions and elements of functional rehabilitation for a certain class of 2-4 storied historical buildings of masonry structure. In order to protect the ornamental plastering of the ceiling, an original technology of rehabilitation for large spanned timber slab structures was performed. The worked out technical solution was applied on several buildings. It is presented on the case of a historical building from the 19th century. This case also gives the opportunity to emphasizing the functional improvement of the building.
