Definitions

• This invention relates to a reinforced load bearing stmcttire and mor ⁇ particulaily to a concrete load bearing structural member and/or slab with a hollow passageway extending through the structural member or slab.
• modem buildings For example, horizontal slabs of steel reinforced concretetypically between 10 and 50 centimeters thick ate frequently used to construct doors for buildings, Ia many industrial buildings, a thick concrete slab supported on a foundation is used, to construct Hie ground floor of a building.

• a more tecent apparatus to provide hollow reinforced concrete floors is disclosed in a U.S. Patent of Breuning, No.5396,747.
• the Braining disclosure utilizes a planar hollow reinforced? concrete floor slab with "two dimensional structure" to obtain higher streng&and stafiEness* less volume of materials, and to obtain a balance between bending forces, shear forces and deformations and reduce the amount of cement.
• the improved reMorced load bearing struci ⁇ ires i B can also be used with the following advantages; reducing the weight of the concrete member due to me hollow area to thereby reduce the flexural movement due to the weight This also means a reduction in cement and steel reinforcement, and increasing the moment of inertia for the member due to the added moment of inertia frame inserted pipe or tube that will lead to a reduction in deflection.
