Abstract2   In structure design practical fields, computer programs like MIDAS and SAP2000 etc. are widely used for the evaluation of the structural performance of the Korean traditional wood structures. It is necessary to use a reasonable analysis model and method for the evaluation of the structural performance. Considering the structural characteristics of the Korean traditional wood structures, it is appropriate to analyze lower frame composed of beam-columns and upper frame which is a roof structure separately. Especially, in the analysis including lateral loads like seismic or wind load etc., it seems to be reasonable to analyze lower frame with an assumption of roof frame as a rigid diaphragm. Because connections between columns and beams have very small rotational stiffness, lower frame may be unstable. So, in the structure design practical fields, connections are modelled by using various assumptions and linear analysis is performed mainly. However, irrationality may be included in these assumptions and analysis method unfortunately. Therefore, in this study, problems in the analysis models and methods for the Korean traditional wood structures, used in structure design practical fields, are investigated first, then some improvement plans are proposed on the basis of investigation results. Because the Korean traditional wood structures may have no high lever stabilities, it is necessary to perform geometric nonlinear analysis. So, geometric nonlinear analysis method including P-δ effect is studied.
