Contribution of RC infills to the seismic behavior of structural systems

Effect of alkali-silica reaction expansion on mechanical properties of concrete Hafçı, Alkan; Turanlı, Lütfullah; Department of Civil Engineering (2013) Alkali-silica reaction (ASR) is a chemical deterioration process which arises in concrete due to reactive aggregate from its constituent, sufficient alkalis from cement or external resources and humidity about 85%. ASR gel, formed by the reaction, absorbs water and expands so that it causes expansion and cracking in concrete. ASR has detrimental effects on mechanical properties of concrete. Therefore, ASR which is a long and a constantly progressive reaction may become a threat to the safety of concrete str...
Effect of soft story on seismic performance of reinforced concrete buildings Akansel, Vesile Hatun; Yakut, Ahmet; Gülkan, H. Polat; Department of Civil Engineering (2017) Real structures are almost always irregular, as perfect regularity is an idealisation that very rarely occurs. Structural irregularities may vary dramatically in their nature and, in principle, are very difficult to define. In comparison with research efforts dealing with horizontally irregular structures, studies aimed at predicting the behavior of structures with rough layouts in elevation are small in number. Due to drawbacks of irregular structures under seismic excitations, engineers are less confident...
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 ...
Effect of ground perlite incorporation on the performance of blended cements Erdem, T. K.; Akgül, Çağla; Tokyay, Mustafa; Erdoğan, Turhan Y. (2007-06-13) Perlite is a volcanic rock that contains relatively high amounts of SiO2 and Al2O3. Due to its proper chemical composition and glassy structure, it can be used as a pozzolanic addition in blended cements. In this study, ground perlite was used as a cement replacement material in blended cements. Several mortar mixes were prepared to investigate the performance of those cements. The results showed that perlite incorporation caused early age strength losses when compared to the control mortars containing only...
Contribution of reinforced concrete infills to seismic behavior of structural systems Canbay, Erdem; Ozcebe, G (2003-09-01) The object of this paper is to report an experimental investigation on the internal force distribution in reinforced concrete (RC) frames with added RC walls. The paper describes a special test setup and force transducers designed to determine the internal forces. The transducers were designed so that the stiffness change in the column would be minimal. The paper reports the results of a test in which a 1/3-scale, two-story, three-bay RC frame was first subjected to damaging lateral-drift reversals and was ...
