Experimental investigations and sensitivity analysis to explain the large creep of concrete deformations in the bridge of Cheviré

In France, the vertical deflection measurements of Cheviré free end cantilever bridge have shown unexpected excessive creep deformations. To understand this phenomenon, a large experimental database coming from different laboratories and research centers is used to compare the creep experimental def...
