PROBLEM TO BE SOLVED: To solve such a problem that since a panel has out-of-plane deformation when a panel zone is hollow whereby a bending moment applied to a beam can not be borne by a web in an elastic area, a section modulus of beam ends used in structural calculation of an architectural construction is the section modules of only a flange excluding the web, and thus the strength of the beam ends is lowered, so that a larger beam has to be used and an extra beam depth is required, which results in an increase in the weight of a steel frame. SOLUTION: The thickness of a diaphragm is largely increased in the direction of the web, and a prestrain is applied by heat wiring or weld padding a lower face of the beam.
