Given data of a reinforced concrete beam: Clear span Factored uniform load Beam width Overall depth Effective depth $=5.5 \mathrm{~m}$ $=30 \mathrm{kN} / \mathrm{m}$ $=300 \mathrm{~mm}$ $=600 \mathrm{~mm}$ $=510 \mathrm{~mm}$ Materials: \[ \begin{array}{l} f^{\prime} \mathrm{C}=24 \mathrm{MPa} \\ \mathrm{fy}=275 \mathrm{MPa} \text { (for shear reinforcement) } \\ \text { Strength reduction factor }=0.75 \end{array} \]




A. Find the factored shear at the critical section if the beam, is supported by a 500mm x 500mm column

B. Find the factored shear at the critical section if framed to a 400mm x 600mm girder.

C. If the beam is reinforced with 3-legs of 10mmØ shear reinforcements spaced at 100mm on centers, determine the shear strength Vu of the section.

D. If the beam carries the given factored uniform load only, find the location from the face of support where the shear reinforcements will be theoretically terminated.
