A 1/13 scaled model tunnel is constructed in order to investigate the blockage effect (the ratio of the model cross sectional area to the tunnel cross sectional area) on the heat release rate inside the tunnel with different ventilation velocities. Scaling is done based on Froude number. In the experiments, wood sticks assembled in different geometrical configurations are burned with various longitudinal ventilation velocities inside the model tunnel. Combustion gases are sampled to calculate the heat release rate. A statistical model is developed using the analysis of variance (ANOVA) method. According to the statistical model, 79.8% of the variation in heat release rate is attributed to changes in blockage ratio, 10.6% to changes in thickness, and 4.5% to changes in velocity.

Effect of AAC Infill Walls on Structural System Dynamics of a Concrete Building Çelik, Ozan Cem (2016-01-01) The effect of autoclaved aerated concrete (AAC) infill walls on the structural system dynamics of a two-story reinforced concrete building is investigated using its finite element structural model, which is calibrated to simulate the acceleration-frequency response curves from its forced vibration test. The model incorporating the AAC infill walls by equivalent diagonal struts captures the increase in lateral stiffness of the building and the torsional motions induced due to the asymmetrically placed AAC in...
Effect of thickness-to-chord ratio on flow structure of nonslender delta wing Gülsaçan, Burak; Ghazijahani, Mohammad Sharifi; Şencan, Gizem; Yavuz, Mehmet Metin (2018-11-18) The effects of thickness-to-chord (t/C) ratio on flow structures of nonslender delta wings with sweep angles of 35 and 45 degrees are characterized in a low-speed wind tunnel using velocity, pressure, and force measurements. The delta wings with t/C ratios varying from 2 % to 19 % are tested at broad ranges of attack angles and Reynolds numbers. The results indicate that the effect of t/C ratio on flow structure is quite substantial. Considering the low angles of attack where the wings experience leading ed...
Effect of Shear Wall Area to Floor Area Ratio on the Seismic Behavior of Reinforced Concrete Buildings Burak Bakır, Burcu (American Society of Civil Engineers (ASCE), 2013-11-01) An analytical study is performed to evaluate the effect of shear wall area to floor area ratio on the seismic behavior of midrise RC structures. For this purpose, 24 midrise building models that have five and eight stories and shear wall ratios ranging between 0.51 and 2.17% in both directions are generated. Then, the behavior of these building models under earthquake loading is examined by carrying out nonlinear time history analyses. In the analyses, seven different ground motion records are applied to th...
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 ...
An experimental study on the effects of blockage ratio and ventilation velocity on the heat release rate of tunnel fires Kayili, Serkan; Yozgatlıgil, Ahmet; Cahit Eralp, O. (SAGE Publications, 2011-8-26) It is very important to accurately predict the fire-induced air velocity, temperature, and smoke concentrations in tunnel fires to design efficient fire protection systems. In this study a scaled model of a tunnel was constructed based on Froude number scaling and wood sticks with different configurations which were burned in a controlled environment. Model vehicles having a square base were built according to the wood crib theory. The impact of varying longitudinal ventilation velocity and the cross-sectio...
