Abstract
This paper deals with the behavior of composite steel beams with openings with the addition of dowel reinforcement. The specimens were built from A36-graded steel plates with a span of 6 m to support a slim floor. The experimental program consisted of four slim beam specimens with and without dowel reinforcement welded at the opening. This paper also studied the load and deflection behavior in the service limit state and the ultimate limit state. The effect of creep on structural behavior was investigated during the long-term loading. A FE model was also studied to compare the load-deflection response of beams from short-term loading. The result found that dowel reinforcement had little impact on energy absorption but significantly increased flexural capacity and stiffness of the composite beams with dowel reinforcement.
