Abstract To improve the traditional fuzzy evaluation method and reflect its nonlinear characteristics, a nonlinear fuzzy evaluation method based on the entropy weight of a structure is proposed according to the construction risk characteristics of the integral hoisting of concrete-filled steel tube (CFST) tied-arch bridge. The risk sources in the construction process of the integral hoisting of CFST tied-arch bridge are associated with structural and personnel safety are considered, and a construction risk level evaluation system is established. A two-level fuzzy evaluation calculation model of the said bridge is established based on the identified results. The the entropy weight of a structure method, which combines the subjective and objective assignment methods, is adopted to calculate the weights of risks. A nonlinear fuzzy algorithm is introduced to reflect the prominent effect of high-risk indicators on the evaluation results. The nonlinear fuzzy evaluation method for the construction risks in a tied-arch integral hoisting of CFST tied-arch bridges is then established. An analysis of an engineering example proves that this method is feasible and effective.
