For the assessment of the safety level of the standing seam roof system with anti-wind clips (SSRS-AWC)

an efficient method was proposed to analyze the reliability of wind-uplifted resistance of SSRS-AWC. Firstly

the mechanical model of SSRS-AWC was established and the corresponding failure criterion was obtained. Then

on the basis of the equivalent extreme-value event

the extended conjugate unscented transformation (ECUT) method

and the principle of maximum entropy

the analysis method for wind-uplifted resistance reliability of SSRS-AWC under multiple failure modes was proposed. Finally

the feasibility of the analysis method was verified by an engineering example. Results show that compared with the Monte Carlo simulation (MCS) method

the maximum relative error of reliability index of proposed method was 0.63%

and the calculation time was only 0.04% of the MCS method

which can accurately and efficiently analyze the reliability of SSRS-AWC under multiple failure modes. The failure probability of SSRS-AWC in descending order was the roof panel tearing damage

the clip rupture

and the clip separation from seam with a probability of 0. It indicates that the addition of anti-wind clips can effectively avoid the clip separation from seam of SSRS-AWC. The failure probability of SSRS-AWC under single failure mode was smaller than that under multiple failure modes. For the sake of structural safety

it is recommended to consider reliability index under multiple failure modes.
