This paper presents a new type of fully bolted H-shaped steel beam-to-column joint. In order to study the hysteretic behavior of the joints, a quasi-static test on four types of new and traditional fully bolted H-shaped beam-to-column joints with different construction methods was carried out. The failure mode of the joint, P-Δ hysteresis curve, M-θ skeleton curve, bearing capacity and ductility were analyzed. The results showed that the hysteresis curve, skeleton curve and mechanical properties of the new fully bolted joints about the strong axis are almost the same as the traditional fully bolted joints. For the behavior about the weak axis, the new fully bolted joints have better hysteretic behavior, higher ductility and stronger bearing capacity than the traditional ones. The yielding bearing capacity, ultimate bearing capacity and ductility increases by 38%, 35% and 32%.
