| Abstract: | Damage of a skew hollow slab bridge is examined. Based on the results of 3-dimensional finite element analysis of the bridge, damage cause and strengthening project with carbon fiber-reinforced polymer externally bonded on tension face of the bridge are presented. Results of field test of the strengthened bridge show that the strengthening is valid. |
