Abstract: The present invention provides a steel frame beam-reinforcing metal fixture that is capable of recovering the full strength of a steel frame beam to a greater extent than a conventional steel frame beam-reinforcing metal fixture for an S structure. A steel frame beam-reinforcing metal fixture is substantially fitted to a web opening in an SRC beam. An outer peripheral portion of the steel frame beam-reinforcing metal fixture is fillet-welded to a steel frame beam web. The axial length of the steel frame beam-reinforcing metal fixture is between 0.5 and 200.0 times the thickness thereof in the radial direction. Furthermore, in the steel frame beam-reinforcing metal fixture, a length from one end side of the steel frame beam web to one end of the outer peripheral portion and a length from the other end side of the steel frame beam web to the other end of the outer peripheral portion are each at least 0.7 times the thickness of the steel frame beam web.

Abstract: The present invention provides a reinforcement design support apparatus and so on for assisting the selection of a reinforcing metal fixture to be used to reinforce a web opening. The reinforcement design support apparatus comprises an application condition determining unit for determining whether or not a web opening provided in a steel frame beam satisfies an application condition on the basis of steel frame beam data and web opening data read from a design drawing, and when application is impossible, correcting the web opening data and re-determining whether or not the application condition has been satisfied, and a selection unit for selecting a reinforcing metal fixture to be applied to the web opening provided in the steel frame beam when the application condition is determined by the application condition determining means to have been satisfied.
