Structural performance evaluation of ECC link slabs reinforced with FRP bars for jointless bridge decks
Graphical abstract Display Omitted
Highlights FRP reinforced ECC link slab ensures a high safety with the rotate of bridge deck. Low reinforcement ratio is suitable to reduce restrain of link slabs on bridge deck. Crack width of 0.1 mm should be adopted to evaluate bending performance of link slab. Proposed FE model can accurately evaluate bending performance of link slab. Design suggestions of link slab were put forward.
Abstract Deterioration of traditional mechanical expansion joints significantly affects the durability of bridge structures. Engineered cementitious composites have been proposed as an alternative to expansion joints in bridge decks. ECC link slabs were cast and tested under monotonic cyclic loading. Link slabs, reinforced with fibre-reinforced polymer bars, demonstrated sufficient flexibility to meet the current design protocols. Nonlinear finite element models were constructed based on the experimental data. Depth-span ratio and reinforcement ratio of such link slabs must not exceed 0.12 and 0.72%. Link slab debonded length should be larger than 0.8% to obtain low bending stiffness.
