Abstract
Castellated beams are broadly output from standard rolled sections, especially in (I) or (H) beam sections, and they are considered as a type of steel members with good properties. From another side, the corrugated web in beam especially trapezoidal pattern was utilized to get an improved beam strength against the shear buckling rupture, Besides, there is an advantage of stability for buckling over a plain web beam. In this paper, an experimental study has been carried out on four beams with the same length (1.7m) under one point load at mid-span. This work deals with two castellated beams with corrugated webs with and without lateral stiffeners and it had the same step length for corrugation and castellation profile. The significant variable for castellated-corrugated web beams is a total height of beams. The ultimate load capacity of castellated-corrugated web beams compared with the plain and corrugated web beams. The results showed that the load capacity of castellated-corrugated web beams without and with lateral stiffeners less than that found in flat and corrugated web beams with (23.7% and 39.4%) and (13.2% and 31.03%). The mode of failure has noticed combined between web post-buckling and flange buckling.
