The feasibility of the use of expanded metal as metal decking in reinforced concrete slabs was investigated experimentally. 8 specimens either flat or having different corrugation geometries were tested. Flat or corrugated geometry of the specimen, strong or weak axis of expanded metal were chosen to be the variables of the test program. It was observed that the material develops excellent bond:with concrete and cracking takes place at significantly high load levels. Finite element models were set up and nonlinear analyses were carried out. The analyses results were in good agreement with the experimental data.

Surface energy and excess charge in (1x2)-reconstructed rutile TiO2(110) from DFT plus U calculations
Unal, Hatice; METE, ERSEN; Ellialtıoğlu, Süleyman Şinasi (2011-09-09)
Physically reasonable electronic structures of reconstructed rutile TiO2(110)-(1x2) surfaces were studied using density functional theory (DFT) supplemented with Hubbard U on-site Coulomb repulsion acting on the d electrons, the so called DFT + U approach. Two leading reconstruction models proposed by Onishi and Iwasawa [Surf. Sci. Lett. 313, 783 (1994)] and Park and coworkers [Phys. Rev. B 75, 245415 (2007)] were compared in terms of their thermodynamic stabilities.
Nickel extraction from Gördes laterites by hydrochloric acid leaching
Göveli, Ahmet; Atalay, M Ümit; Department of Mining Engineering (2006)
Leaching is the most widely used process for extraction of nickel metal from lateritic ores. In this study, nickel extraction from Manisa-Gördes region laterites by hydrochloric acid leaching is aimed. The mineralogical analysis of sample showed that hematite, goethite, dolomite, quartz and smectite are the main minerals in the ore. Attrition scrubbing, cycloning and magnetic separation with permroll were used as preconcentration processes but results were unsatisfactory. HCl leaching experiments were condu...
Seismic upgrading of reinforced concrete frames with structural steel elements
Özçelik, Ramazan; Binici, Barış; Department of Civil Engineering (2011)
This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant grav...
Composite shear stud strength at early concrete ages
Topkaya, Cem; Williamson, EB (American Society of Civil Engineers (ASCE), 2004-06-01)
Composite action between a reinforced concrete deck and steel girders is usually achieved by making use of welded headed shear studs. The mechanics of shear studs embedded in mature concrete has been investigated extensively in the past. Current literature, however, lacks experimental evidence of steel-concrete interface behavior at early concrete ages. This information is useful in understanding the behavior of bridges during construction. Current testing methods are not suitable for determining the respon...
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...
