title = "Advanced flexibility-based element allowing for member imperfection and shear deformation",
abstract = "In this paper, a new flexibility-based beam-column element, allowing for the interaction of shear effects and initial imperfection, is proposed. The element is formulated with Hellinger-Reissner function and locking-free with exact force interpolation functions. An extended displacement interpolation based on the curvature and shear strain is adopted to account for shear deformation. The member imperfection is considered along with the member length, and only one-element-per-member is required for structural analysis to achieve reasonable and accurate solutions. The distributed plasticity is taken into account by fiber section approach. Two numerical examples demonstrate the accuracy and efficiency of the proposed element.",
