Recently, owing to the development of computer program, MAny commercial programs are used for the modelling and structural analysis of Korean Traditional Wood Structure(KTWS). For structural analysis of KTWS by computer program, It is important that each element of total structure and joints are reasonably modelled. Existing modelling method of joints assumes that the joint is end moment released beam element or semi-rigid beam element which rotational stiffness is evaluated by private experience. So, the purpose of this study is to find the rational estimation method on the rotational stiffness of joint for upgrade of believability in structural stability estimation of KTWS.
