Abstract:
To solve the disease of hinged joint in the existed prefabricated voided slab bridges, a new type of prefabricated inverted T-shape voided slab bridge was presented. The full-scale model experiment and the nonlinear finite element analysis on the inverted T-shape voided slab bridge with 8 m span were conducted. The stress, deflection and crack distributions of each component of inverted T-shape voided slab bridge subjected to the vehicle load were analyzed. The force mechanism and failure mode of inverted T-shape voided slab bridge were obtained. The mechanical behaviors of inverted T-shape voided slab bridge and voided slab bridge with gate-type steel bars were compared. The effectiveness of inverted T-shape voided slab solving the problem of cracking in hinged joint was verified. Research result shows that the failure process of inverted T-shape voided slab bridge can be divided into the elastic stage, cracking stage of voided slab, cracking stage of concrete in the field-cast structure layer, and yielding stage of tensile steel bars and steel plates. The inverted T-shape voided slab bridge have a good overall mechanical property, its ultimate capacity is 1.4 times of that of voided slab bridge with gate-type steel bars. The concrete in the tensile area above the Ω-shape steel plate is a weak part, forits tensile stress firstly reaching the limit 3.17 MPa. Due to the existences of Ω-shape and L-shape steel plates, when the concrete in the field-cast structure layer cracks, the normal and tangential bonding stresses of each junction surface as high as the field-cast structure layer will not exceed their limit 2.30 and 0.29 MPa, respectively, avoiding the bonding failure on the junction surface. Comparing with the mechanical property of voided slab bridge with gate-type steel bars, the inverted T-shape voided slab structure does not reduce the cracking load of voided slab, and the junction surface between the old and new concretes cracks after the cracking of voided slab. It can fundamentally solve the problem that the hinged joint cracks before the cracking of voided slab under the vehicle load. 2 tabs, 30 figs, 30 refs.
