Experimental study on the behavior of asymmetrical castellated composite girders under effect of repeated loads

This paper studies the flexural experimental behavior of an asymmetric castellated composite beam with an encased steel web by RPC (reactive powder concrete) casting in a steel web beam as a composite member with and without lacing rebar under the effect of repeated loads. The cross-section is made from steel beams and concrete deck slabs. The steel beam (asymmetric section) is made from two parts of the tee section; the top part was cut from IPE 180, and the bottom was cut from IPE 200. Use RPC to strengthen the steel web with and without rebar lacing. The results show the difference in ultimate service load capacity by (+14.56) with RPC without rebar lacing and (+23.84) with RPC with rebar lacing under repeated loads.
