Rotation capacity assessment in developed non prismatic flanged reinforced concrete Tee beams
Source abstract
Abstract
Flanged reinforced concrete beam of Tee section is an optimal member and has special importance in civil engineering for its efficiency in structural fields to maximize strength capacity. The flexural ductility in reinforced concrete beams is a complex nonlinear phenomenon dominated by plastic rotation capacity. This paper introduces and assesses rotation capacity improving in Tee- section reinforced concrete beams of a proposed tapered flange configuration. The special section area distribution in proposed reinforced concrete Tee beams intends to introduce smart configuration regards tapering benefits besides flange section benefits to upgrade the rotational capacity besides other structural characteristics. Twelve reinforced concrete beams have been fabricated and tested; which are classified into nine specimens of non-prismatic flanges, one specimen of rectangular section, two specimens of T- section of upper and lower tapered flange thickness of considered nine sections. The main experimented parameters are non- prismatic flange domain, and web thickness. The results confirmed the positive effectiveness of considered in plane non-prismatic flanges within T-section upon elastic and ultimate deflection curves, plastic rotational capacity upgrading and plastic hinge development without any significant effect upon ultimate load capacity and flexural stiffness.
