Abstract
In last years, a new trend in the construction of short and medium span bridges has raised in some countries. The solution of an Integral Abutment Bridge (IAB), when possible to do, reduces the cost of construction and maintenance because expansion joints and bearings are not necessary. With the development of reliability approach, it is possible to develop a probabilistic analysis of a structure to study the behavior of the bridge in a more realistic way. A big effort has done in the present years to realize different reliability studies on bridges, but only focused on gravitational loads, without paying much attention to temperature, creep, shrinkage and the interaction of the soil and the structure by the stiffness of the soil around the infrastructure. This work will develop the state of art on literature for the study of this kind of variables in a probabilistic analysis of IAB.
