The proposed technique has been applied on a nonlinear stall flutter aeroelastic system to quantify the propagation of multiparametric uncertainty from both structural and aerodynamic parameters. Their relative importance...

... and replaced bridges built in U.S. in 2009. Furthermore, they make up 9% of all structurally deficient bridges in the U.S. Prestress loss is one of key reasons for the structural deficiency of prestressed bridges. Big loss of prestress would cause malfunction and even collapse of a prestressed bridge, which...

Based on the proposed procedures, various structural examples with an interval and fuzzy parameter such as triangular fuzzy number (TFN) are investigated to show the efficiency of the algorithms stated. Finally, fuzzy...
