To establish a numerical analysis method for appropriately evaluating moment-rotation relation of top- and seat-angle connections under cyclic loading, three-dimensional elasto-plastic finite element analysis was performed under following considerations: 1) all the connection components are modeled using solid elements; 2) a contact surface algorithm is applied between every adjacent two components; and 3) bolt pretension is introduced. An applicability of this analysis method for this type connections was discussed comparing with the experimental results. The results obtained from this study are as follows: 1) applying the proposed analysis method, envelope curves on hysteretic moment-rotation relation of top- and seat-angle connections can be accurately predicted regardless of the magnitude of longitudinal length of web angle; and 2) strain distribution of top and/or web angle can be qualitatively estimated by using the proposed method.
