Title

STATISTICAL EVALUATION OF ROTATION CAPACITY OF MOMENT CONNECTIONS

Authors

Abstract

The paper describes the reasons that cause rotation capacity of moment connections strongly dependent on material properties of components of such connections. Then a statistical evaluation of the rotation capacity of typical moment connections with respect to the variation of the material properties of individual components was performed. The Monte Carlo method was used and 10,000 calculations were performed in each analysis. Log-normal distribution was assumed for yield strength fy and ultimate strength fu with the range of typical mean values and coefficients of variation from literature. The results show that considerable variation in rotation capacity is obtained in some cases.
