One-dimensional fiber beam-column model and two-dimensional fixed crack model for numerical simulation of UHPC structures

•Uniaxial skeleton and hysteretic rules for UHPC are proposed with convenient parameter calibration.•2D fixed crack model for UHPC which can account for nonlinear shear behavior is proposed.•Fiber beam-column element and fixed crack model based shell element are implemented in FEA software.•Six R/UHPC columns, ten R/UHPC shear walls and four R/UHPC beams are simulated and validated.
