The purpose of this study was to propose the initial stiffness of steel welded beam-to-column connection. To simplify the analysis, neglect the influence of welding and fillet of H-section beam. According to the parameter(ζ), initial stiffness(K_(i)) increased by ratio of section modulus(Z_(b)/Z_(c)) and decreased by ratio of width/thickness. Result of analysis, range of moment resistance is 0.50M_(F)~1.00M_(F) (Unstiffened Welded Connection), 0.77M_(F)~1.00M_(F) (Continuity Plates Welded Connection) and initial stiffness(K_(i)) is 1.36×10^(8)~24.5×10^(8)(kgf·cm)(Unstiffened Welded Connection) 3.79×10^(8)~33.3x10^(8)(kgf·cm)(Continuity Plates Welded Connection).
