Abstract
The buckling strength of a structure depends hugely on material properties, geometry dimensions, and boundary conditions that are potentially random. This paper presents an assessment of the safety of buckling strength of steel plane frame semi-rigid beam-column connections. The Newton-Raphson method is used to solve the nonlinear equation for the buckling limit of the column. The reliability of the structure is evaluated by the Monte Carlo simulation method. The effects of input parameters are also investigated.

Summary
The analysis of steel frame with semi-rigid connections is always an interesting research topic. Research and application of the stiffness matrix method to analyze the plane frame with semirigid connections, in which the stiffness matrix and nodal force vector of each element depend on the linear stiffness of the connection, was conducted in [4]. A novel method to analyze the spatial frame considering the material nonlinearity and large deflection effect was presented in [5]. Stiffness analysis on semirigid joints in gabled frames was studied in [12], and the elastic buckling of end-loaded, tapered, cantilevered beams with initial curvature in [13]. In this research, buckling analysis of steel gabled frames with tapered members and flexible connections was used
