Behavior of Steel-Concrete Composite Beams Under Fatigue Loads

Numerical investigation of steel-concrete composite (SCC) beam subjected to combined blast-impact loading

“…Previous numerical studies [10,11] characterized on response of SCC beams when imposed with fatigue loads. El-Zohairy et al [10] showed a systematic approach that can be used to enhance strength of composite system such as pre-compressing steel bottom flange to minimize tension portion of stress limit which in turn improves load carrying capacity of a SCC beam.…”

Also, Deviyathi and Mohan [11] indicated composite beams are unlikely to fail in shear even under low shear span to effective depth ratio when subjected to increased number cycles of reverse loading conditions.…”
