The flexural response of non-laced reinforced concrete elements is demonstrated through the resistance-deflection curve of Figure 4-1. For elements without shearreinforcement, the ultimate deflection is limited to deflections corresponding to 2degrees support rotation whereas elements with shear reinforcement are capable ofattaining 6 degrees support rotation. For ease of construction, single leg stirrups (Figure4-2) are used as shear reinforcement in slabs and walls. This type of reinforcement iscapable of providing shear resistance as well as the necessary restraint of the flexuralreinforcement to enable the slab to achieve this increased deflection.
