that the adhesive layer between the steel beam flange and concrete does not have a significant effect on the final capacity of the push-out specimen but only on its initial stiffness. Therefore, during concreting, an attempt was made to prevent the adhesion of concrete to the flange of the steel beam by using grease.

The essence of steel in a reinforced concrete structure, such as a beam, can be summarized in the following key points:

When tensile stress is applied on a beam axially. What happens?*

What target strength was your concrete mix being designed fo

Compressive Strength of Concrete

the beam has a maximum design moment of 272 kn-m. the beam is limited to a cross-section of 250mm x 460mm, having an effective depth of 400mm. fc' = 20.7 mpa, fy = 344.7 mpa. use a steel covering of 60mm on both the top and bottom. a) design the reinforcement steel rebar at the bottom of the beam. b) design the reinforcement steel rebar at the top of the beam. c) is the tensile steel yields? show your solution
