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.　©　2016　Taylor　&　Francis　Group,　London.
