2.2 RC Beam Configurations
All RC beams prepared in the all series have the same overall
cross sectional dimensions, longitudinal main reinforcement
and stirrup arrangements. Each beam is 250 mm high, 150 mm
wide, 2325 mm long and 2025 mm long between support to
support as shown in Figure 2. Each beam is reinforced
longitudinally by two 12 mm diameter high yield strength
steel bars positioned below the neutral axis of the beam to
cater for the tension force, while two 10 mm diameter mild
steel bars are used as tie bars located at the compression side
of the beam. The beams are designed to be over reinforced in
resisting internal shear force to ensure that the beams would
fail in pure bending or flexure. The shear reinforcement
