Studies on the behavior of composite beams under negative bending have been conducted experimentally and theoretically and discussed in the previous bulletins. The previous experimental study was limited within static loading, and the present study is to investigate the behavior of composite beams under repeated negative bending. Test beams consists of composite beams with studs spaced normarly and with studs spaced at the beam ends. Call the latter beam as a "partial composite beam" herein. Special attentions are paid to the bending stiffness, efficiency of slab reinforcing bars, maximum crack width, crack pattern, residual stress in the reinforcement, residual crack width and ultimate strength. High cycle loading and low cycle loading are applied on the basis of the design load and of the ultimate strength based on the nominal yield stress, respectively. Static test is also conducted after the fatigue test. Following conclusions are obtained from the present study. (1) Relationships between load and deflection become close to the theoretical ones gradually as increasing number of loading. (2) Slab reinforcement is effective to bending, however reisdual stress in the reinforcement increases as the increase of number of loading. (3) Apparent difference of maximum crack width does not occur between complete and partial composite beams. The relationship between maximum crack width and stress in slab reinforcement is expressed as linear. (4) No difference of ultimate strength is shown between complete and partial composite beams after fatigue test. |
