| Abstract: |
| A numerical code named MFPA was used to study the initiation and propagation of cracks in FRP retrofitted concrete structure under external static loading.The basic characteristics during the crack propagation was clarified.In particular, the effect of parameters of adhesive layer on the loading capacity of FRP retrofitted structures was studied,and the two typical brittle failure patterns occurred in the concrete structures were numerically investigated. |
| Key words: fiber reinforced plastic(FRP),concrete structure,crack propagation,numerical (simulation) |
