This paper describes an experimental study on European channel shear connectors. While shear studs are widely used in steel-concrete composite elements, the channel connectors are also gaining popularity due to their certain advantages. The channel connectors do not require special equipment and standard welding procedures are adequate for attachment purposes. In addition, this type of connector offers higher amounts of shear resistance due to its high contact area with surrounding concrete. Although first studies date back to 1950s. little work has been done in the past to investigate their behavior. Majority of the work done to date was on channel connectors used in North America with a very limited parameter range. An experimental study consisting of 15 push-out tests was carried out to investigate the behavior of European type channel connectors with various heights and lengths. The ultimate resistance of the connectors obtained from experiments was compared against those predicted by North American steel design specifications. It was observed that the equations presented in American and Canadian specifications are too conservative. Based on a model that represents the typical failure mechanism in push-out tests, a new equation was developed for the ultimate resistance of channel shear connectors. It is shown that the developed equation is capable of predicting the ultimate resistance of channel connectors with reasonable accuracy.

Behavior of steel-concrete partially composite beams with channel type shear connectors Baran, Eray; Topkaya, Cem (2014-06-01) This paper summarizes the findings of an experimental study investigating the flexural behavior of partially composite beams incorporating channel type shear connectors. Results from monotonic load testing of four full-scale steel-concrete composite beams and a steel beam are presented. The main effort focused on identifying the variation of strength and stiffness properties of beams with various degrees of partial composite action. Behavior of channel shear connectors in the composite beam specimens is rel...
Comparative evaluation of steel mesh, steel fibre and high-performance polypropylene fibre reinforced shotcrete in panel test Cengiz, O; Turanlı, Lutfullah (2004-08-01) In this study, experimental investigations were performed on steel mesh (SM), steel fibre (SF) and high-performance polypropylene fibre (HPPF) reinforced shotcrete (HPPFRS) panels to evaluate performance characteristics such as toughness, flexural ductility, energy absorption and load capacity. The panel tests, in accordance with European specification for sprayed concrete (EFNARC), were made on 18 prismatic specimens having the same mix designs and were cured for 28 days but reinforced with various fibres....
Numerical investigation of stiffened composite panel into buckling and post buckling under combined loading Akay, Erkan; Yaman, Yavuz; Department of Aerospace Engineering (2015) This thesis presents the investigation of buckling and post buckling behaviour of stiffened thin walled laminated composite aerospace structures subjected to combined in-plane axial and shear loadings. Due to the fact that the state of stress developing especially in the post-buckling stage is quite complicated under the combined loading, the necessary computational model is usually based on Finite Element Modelling (FEM). In this study, after verifying the FEM methodology and completing the sensitivity stu...
Evaluation of separate channel methods for discharge computation in asymmetric compound channels Al-Khatib, Issam A.; Dweik, Adel A.; Göğüş, Mustafa (2012-04-01) Some experimental results from the Fluid Mechanics Water Channel Facility at Birzeit University, Birzeit, Palestine, were used for computing discharge using separate channel methods in asymmetrical compound channels with varying floodplain widths and step heights. Three assumed interface planes (vertical, horizontal and diagonal) between the main channel and the floodplain subsections were considered. Then discharge values in the subsections and in the whole cross-section were evaluated. None of the separat...
A computational model for reinforced concrete members confined with fiber reinforced polymer lamina: Implementation and experimental validation Mosalam, Khalid M.; Talaat, Mohamed; Binici, Barış (Elsevier BV, 2007-7) This study presents a computational model to simulate the behavior of confined concrete in column plastic hinge zones. The model describes the distribution of confining stresses within a circular column cross-section and the hysteretic behavior of concrete under passive confinement. Of particular interest is the ability of the model to predict the maximum circumferential strains and thus estimate the limit state of the confining medium rather than relying on empirical limits such as concrete compressive str...
