This study investigates characteristics on inelastic flange local buckling of ultra high performance concrete (UHPC) plate supported by one edge. The UHPC plate were modeled using 3D shell elements (S4R) and analyzed using by geometric and material nonlinear analysis. The plates for FE analysis were supported by pined and fixed boundary conditions to considering constrained effects of one web. The inelastic local buckling strength from the FE analysis were evaluated according to the flange slenderness ratios. The results shows that material non-linearities of tensile behavior of UHPC highly affects the inelastic local buckling of UHPC plate.
