Traditionally, semi-rigid analysis of extended end plate connections is assumed to be deterministic
parameters. Most of the moment-rotation models of the joint are determined by curve-fitting and statistically
regressed with the test data. Parameters of these models have little physical meaning, and the effect of correlations
in the parameters is neglected. This paper deals with a semi-rigid joint of extended end plate connections based
on correlation and sensitivity analysis. A numerical study was carried out and the finite element analysis was
validated compared with the experimental results. The relative moment-rotation model was concluded based on
correlations in parameters and probabilistic sentivity analysis. The relationship between height and width of steel
beam was partial correlation. The relationship between thickness of steel beam flange and thickness of steel beam
web was also partial correlation. Height and width of steel beam, and distance of upper bolts to axle wire of steel
beam section were important sensitive parameters for the extended end plate connections.
