Abstract EN
Deep beams are structural elements that commonly design for bridges, girders, foundation walls, pile caps and others.
Also, using Self Compacting Concrete (SCC) mix for deep beam is a suitable choice for deep beams because of reinforcement congestion therein.
The main objective of this work is to study the shear capacity of SCC reinforced concrete deep beams subjected to axial load, so that both of experimental and analytical works are done.
The experimental work consists four simply supported deep beams casted by using SCC mix with steel fibers and tested.
All these beams have dimensions 1300mm length, 350mm high, 150mm width and have been subjected to axial force with (100) kN value and then subjected to two-point loads.
The variables of this work are vertical and horizontal shear reinforcement and steel fibers ratio in order to study their effects on first crack load and ultimate load and mid span deflection.
From the experimental results obtained all the tested beams failed by diagonal splitting mode with some crushing at support zones (in some beams).
The second part is the analytical study of this research, including presents proposed equations to estimate the mechanical properties as: compressive strength f`cf, splitting tensile strength ftf, modulus of rapture frf, and modulus of elasticity Ecf of fibrous SCC.
