reinforcement.As the element is further deflected, the reinforcement enters into its strain hardeningregion, and the resistance increases with increasing deflection. Single leg stirrups willrestrain the compression reinforcement for a short time into its strain hardening region.At six (6) degrees support rotation, the element loses its structural integrity and fails. Onthe other hand, lacing through its truss action will restrain the reinforcement through itsentire strain hardening region until tension failure of the reinforcement occurs at 12degrees support rotation.
