This paper evaluates the behavior of channel shear connectors, embedded in a concrete slab, with different concrete materials. The results of a series of limited push-out specimens were presented and discussed. The push-out tests comprise of channel shear connectors in different types of concrete. Reinforcement was included in some specimens, as well. The results showed that using reinforcement...

Post-earthquake observations and laboratory tests reveal the needs for innovative solutions that can enhance concrete compression ductility in boundary elements of special structural walls. This study proposes a new element design by utilizing hybrid fiber reinforced (HyFRC). One full-scale HyFRC is tested uniaxial compared to three conventional are compliant with ACI-318 codes. Results demonst...

Rice Husk Ash (RHA) is natural Pozzolan containing reactive silica and/or aluminum. When the material is mixed with lime in powdered form and in the presence of water, it will set and harden like cement. This work uses Osadebe’s optimization model to optimize the shear modulus of concrete made from RHA. The strengths predicted by the model are in good agreement with their corresponding experime...
