Latin Hypercube Sampling Based Uncertainty Simulation of Concrete Time Effects

Latin hypercube sampling based uncertainty simulation of different concrete time effect models was researched in this paper.Firstly,the past results of uncertainties of concrete time effect models were summarized.The three models uncertainties of the concrete time effect were compared.Then the simulation method of Latin Hypercube Sampling(LHS) was introduced.The uncertainties of the concrete time effect model,the given concrete properties and the given ambient environment were simulated by the LHS.And the simulated results were analysed.The results indicate that B3 model and CEB-FIP90 model are preferred to forecast the uncertainties of the concrete shrinkage and creep respectively.
