Abstract:

Use of castellated beam for high bay span steel structures, parking structures, office buildings, health care buildings etc., increases substantially in the recent scenario because of its outweigh advantages. The objective of the castellated beam is to improve load-carrying capacity without increasing its weight to full fill loading criteria and serviceability criteria. Therefore, in this research work, non-linear numerical modelling analysis is carried out to observe the behavior of castellated beams having a newly proposed irregular shape of the opening. Curve-in-curve (Arch) type of opening shape is prepared from the parent ISMB 250 section. The finite element model was prepared using ABAQUS/CAE 6.11 version. The average load-carrying capacity of a curve-in the curve type of opening increases by 27% and 15% for circular and hexagonal shaped castellated beams respectively. Two different parameters considered for analysis of curve-in the curve type of opening castellated beam in this paper is (1) the length of its first opening provided from the end support condition of the beam and (2) load-displacement variation of a curve-in the curve type castellated beam prepared from parent ISHB 450 section for its varying web thickness. An increment in load-carrying capacity is also measured for both the models having reinforcement around the web opening.

Curve-in the curve shape opening, Castellated beam with and without reinforced novel-openings, Length of 1st arch opening from the end of the beam, Castellated beam with different web thickness, ABAQUS.
