Web Rotational Stiffness of Continuous Steel-Concrete Composite Castellated Beams

Abstract: Continuous composite beams can present a global instability known as lateral distortional buckling (LDB). The design code EN 1994-1-1:2004 provides a procedure for the verification of this ultimate limit state, in which the resistant bending moment is calculated considering the behavior of the inverted "U-frame" mechanism. An essential parameter for the determination of this moment is the rotational stiffness of the composite beam, which depends on the web stiffness. The EN 1994-1-1:2004 procedure is restricte… Show more

“…In the present study, the finite element analysis is carried out for solid beam and castellated beams of depth 150 mm, 225 mm to determine their maximum load-carrying capacity, deflection, and stress. [6][7][8][9] A 3-D finite element (FE) model is established to replicate the behaviour of solid and CBs having the cross-section of I-shaped with FE packages ANSYS 16.0 and19.2.…”
