  • Combining Monte Carlo sampling with nonlinear finite element method, the random analysis model for nonlinear deflection of reinforced concrete beams was established to assess the random deflection of in-service reinforced concrete beams. Based on this model, the stochastic deflection of the classic concrete beam in loading process was simulated. Meanwhile, the parametric analysis of reinforcement ratio of concrete section was performed. The results show that the variability of deflection changes in loading process. Under the loads of high probability of cracking, the variability of deflection reaches the maximum value. Moreover, the variability of deflection is affected by the reinforcement ratio. The lower reinforcement ratio leads to the higher variability of deflection. However, with the increment of the load, the variability of deflection is reduced. Finally, when the load is close to the serviceability limit state, the variability of deflection for different reinforcement ratios becomes stable and similar.
