Stub girder floor system.

18 2 description of the stub girder floor system the main element of the system is a special girder fabricated from standard hot rolled wide flange shapes that serves as the primary framing element of the floor. A stub girder floor system is a composite system constructed from a continuous steel beam and a reinforced concrete slab separated by a series of short typically wide flange sections called stubs. The test results indicated that the stub girder with the modified end details is structurally as efficient as the conventional system. The structural system consists of wide flange beams spaced between 7 ft 0 in and 11 ft 0 in.

The concrete slab was continuous over the end supports of the interior span. The test specimens were designed as spandrel stub girders for a typical office floor loading and consisted of three continuous spans. The floor slab consists of approximately 3 25 in. A stub girder floor system is a composite system constructed from a continuous steel beam and a reinforced concrete slab separated by a series of short typically wide flange sections called stubs.

The finite element method has been used in the analysis of this composite system where it is capable to represent the constituent parts adopt. The stub girder floor system shown in fig. Early 1970s the system aimed at providing construction economies through the integration of the. Hot rolled wide flange shapes are also used as transverse floor beams running in a direction perpendicular to the main girders.

The stub girder system was developed in response to a need for new and innovative construction. A conventional system of framing a floor in a structural steel structure is shown in fig. This system is called a stub girder system.
