title = "GBT-based Vibration Analysis of Cracked Steel-Concrete Composite Beams",
abstract = "This paper presents a computationally efficient finite element, based on Generalised Beam Theory (GBT), that enables assessing the vibration serviceability limit state (the calculation of undamped natural frequencies and vibration mode shapes) of steel-concrete composite beams, accounting for concrete cracking and cross-section in-plane and out-of-plane deformation. It is shown that the modal decomposition features of GBT enable an in-depth characterisation of the vibration modes. A numerical example is presented to illustrate the accuracy and efficiency of the proposed element, through comparison with refined shell finite element model results.",
