Web crippling of thin-walled members is often observed at loading or reaction points where concentrated forces exist. This paper reports an investigation on using CFRP (carbon fiber reinforced polymer) strengthening technique to improve the web crippling capacity of aluminium RHS (rectangular hollow section). Several types of strengthening technique were adopted in this project. They include applying CFRP plates outside or/and inside the RHS. A series of laboratory tests were conducted. Significant increase in load carrying capacity was obtained. The test results are also compared with those for cold-formed steel RHS strengthened by CFRP.
