Abstract
This paper presented the experimental study on two different strengthening methods for partially damaged timber columns, GFRP (Glass Fiber Reinforced Polymer) sheets and sprayed FRP (Fiber Reinforced Polymer). Detail comparison was carried out between the mechanical properties of 25% or 50% damaged timber short columns under uniaxial or biaxial eccentric compression. The ultimate bearing capacity of retrofitted columns increased obviously. The biggest improvement after SFRP (Sprayed FRP) retrofitting was 62.7%. Compared with that of undamaged columns, the ultimate bearing capacity of partially damaged columns after retrofitting was recovered up to 48 to 98%. SFRP method is a reasonable and better substitute method of GFRP sheets retrofitting.
