内容記述 |
Partial composite beams have been practiced in the United States and Canada, but the partial composite beams with partly complete interaction in the negative bending region are not included in the highway bridge specifications. However, from theoretical analysis, the stiffness of partial composite beams with partly complete interaction is greater than that of partial composite beams without shear connectors in the negative bending region and reinforcement strains do not significantly increase comparing with the increase of the bending stiffness. Three composite beams are tested in order to provide additional information on the bending behavior of the partial composite beams. The test beams varied in terms of shear connector spacing. Special attentions are paid to the bending stiffness, efficiency of reinforcing bars, crack pattern, maximum crack width, residual crack width, slip and deflection. High cycle loading is applied on the basis of the design load. The following conclusions can be drawn from the present study; (1) Relationships between load and deflection become close to the theoretical ones gradually as increase of the number of loads. (2) The reinforcement in the concrete slab is effective to bending, however the residual reinforcement stresses increase as increase of the number of loads. (3) The residual crack width and maximum crack width at the design load do not increase due to increase of the number of crack. (4) The relationship between maximum crack width and reinforcement stress is approximately linear. (5) Little difference of ultimate strength arises among three composite beams. |
