In this paper, a new design method of tension-type connections with long-through bolts is developed and their structural properties are investigated by several tests. Summary of results obtained may be as follows ; This type connections have efficient deformation capacity by the restraint of the beam end-plates. The decrease of the introduced axial forces of bolts has a little effect on the load-deformation characteristics. The stiffness of the long-through bolt may be evaluated as that the stress transmission angle is about thirty degress. It is proper to consider that the short-time strength is about seventy percents of the breakage load of the connection.
