In this paper, the effect that the joint efficiency (that is, the bending moment conductivity) of a web at a beam-to-column connection has on the deformation capacity of a steel beam is evaluated by the gross sectional average strain of a beam flange. First, the formula that describes the relation between the joint efficiency and the gross sectional average strain of a beam flange has been derived from the simple theory based on experimental knowledge. Next, the gross sectional average strain of a flange and the joint efficiency of a web have been investigated by the monotonic bending test of the steel beam specimens, the joint efficiency of which is varied. By the results of this test, it has been verified that the joint efficiency of a web is predictable by using results of existing researches. Finally, the proposed formula is compared with experimental results, and it has been confirmed that the gross sectional average strain of a flange is predictable from the joint efficiency of the web by using the proposed formula.
