Patent ID: 8595937

Claim:
A method for fabricating a reinforced concrete wide shallow beam with increased shear resistance efficiency, comprising the steps of: providing a plurality of rebars; positioning said rebars in a parallel orientation to form an internal structure of a beam; providing a plurality of stirrups; positioning said plurality of stirrups around said plurality of rebars; calculating an effective depth (d) of said plurality of rebars after said plurality of rebars have been positioned to form said internal structure of a beam; calculating a longitudinal spacing (s L ) of said plurality of stirrups, wherein said longitudinal spacing (s L ) is comprised of a horizontal distance between each of said plurality of stirrups; providing a plurality of legs; determining a practical value for a transverse spacing (s w ) of said plurality of legs, wherein said transverse spacing (s w ) is comprised of a horizontal distance between each of said plurality of legs; calculating an equivalent spacing (s eq ), wherein said equivalent spacing (s eq ) is calculated by s eq = ( s L d ) 0.25 ⁢ s L ⁢ s w ≥ s L ; calculating an efficiency factor (λ), wherein said efficiency factor (λ) is calculated by λ= S L /S eq ; maximizing said efficiency factor (λ) by repositioning said plurality of legs and said plurality of stirrups; and enclosing said plurality of said repositioned of legs, said plurality of said repositioned stirrups and said plurality of rebars in concrete to form said reinforced concrete beam.
