چکیده
Aiming to investigate the mechanical performance of UHPC T-section beams, five specimens are fabricated and tested, considering variable steel fiber volume fraction (SFVF). The code Association Francaise de Génie Civil (AFGC) is evaluated by test data. Additionally, based on Abaqus (2020), refined finite element analysis (FEA) models established validated experimental Moreover, parametric sensitivity carried out, which aims further effect shear span ratio, longitude reinforcement stirrup ratio bending-shear behavior beams. results indicated that ultimate load specimen improves with increase SFVF, use fibers can greatly improve capacity instead bending capacity. Furthermore, SFVF change failure mode; fail in when < 2%, while they ≥ 2%. From evaluation codes, AFGC conservative prediction capacity, guide design structures well. from FEM, mode transformed as increased, particularly 2.5%. ρsv has a significant ≤ 1%, it less

Ultra-high performance concrete (UHPC) is a developing concrete and today is increasing to interest using it in structures due to its advantages such as high-compressive strength, modulus of elasticity, highly durability and low-permeability. Therefore, it is necessary to provide models for prediction of nonlinear behavior of this material. This study is aimed to investigate the tension-stiffen...
