Stub Girder Floor System

The stub girder floor system shown in fig.

Stub girder floor system. The test specimens were designed as spandrel stub girders for a typical office floor loading and consisted of three continuous spans. 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. Of lightweight concrete on a metal deck. The floor slab consists of approximately 3 25 in.

The concrete slab was continuous over the end supports of the interior span. Stub girder floor systems. This system is called a stub girder 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 finite element method has been used in the analysis of this composite system where it is capable to represent the constituent parts adopt. Early 1970s the system aimed at providing construction economies through the integration of the. 1 is one of the structural methodologies that attempts to minimize floor to floor heights by incorporating services within the structural depth the use of the stub girder floor system generally reduces the amount of structural steel in the floor system by about 25 and the total cost of the floor system by about 15.

The structural system consists of wide flange beams spaced between 7 ft 0 in and 11 ft 0 in. The test results indicated that the stub girder with the modified end details is structurally as efficient as the conventional system. Hot rolled wide flange shapes are also used as transverse floor beams running in a direction perpendicular to the main girders.
