    Abstract
  • Stiffness coefficient describing the rigidity of end-plate connection is defined based on the formula that was obtained by component method to calculate the initial stiffness of end-plate joint.A simplified expression for the initial stiffness is then deduced taking stiffness coefficient as main variable.By parameter analysis for the initial stiffness of end-plate joints in slender steel frames,the expressions of stiffness coefficient under different joint constructions are fitted.Accordingly,stiffness coefficient method to calculate the initial stiffness is developed.The method behaves with enough accuracy as compared with the results of tests and finite element analysis.So does the short-cut methods which is derived at the same time.
