Effectiveness of helical binding in compression zone of concrete beams
Reinforced and prestressed beams were tested by midspan loading to investigate efficiency of helical reinforcement in compression zone as means of improving moment-rotation characteristics of plastic hinges that formed; helices were generally more efficient than stirrups in terms of weight of steel for specified increase in plastic rotation; rectangular stirrups tended to deform outwards and permit compression zone to crush; balanced section reinforced concrete beams and rectangular prestressed beams were given adequate plasticity by helices alone, but over-reinforced beams generally required additional shear reinforcement in form of stirrups.
