The purpose of this paper is to clarify a bending moment share of beam web in the flange welded - web bolted beam-to-column joint. Static cyclic loading tests (for two type specimens of full scale beam-to-column joint) were carried out. One is the flange welded-web bolted joint (specimen F) and the other is the web bolted joint only (specimen NF). The flange fracture occurred in case of specimen F and the shear fracture of bolt occurred in case of specimen NF. The bending moment share of bolted joint web was make clear by comparing the load-deflection relationships of the two specimens.
