Experimental Study on Mechanical Properties of Timber Columns Strengthened with Carbon-Aramid Hybrid FRP Sheets under Axial Compression
Based on the experiment of timber circular columns made of pine and fir confined by carbon-aramid hybrid FRP (HFRP) sheets under axial compression, the failure modes, axial bearing capacities, peak compression strains were analyzed. The results showed that: Compared to the unconfined specimens, the axial bearing capacities and peak compression strains of the specimens confined by HFRP sheets were all improved. Axial bearing capacities of pine and fir specimens improved 6.6％～16.8％ and 5.0％～16.9％,respectively. Peak compression strains of pine and fir specimens improved 8.9％～60.2％ and 11.5％～56.8％, respectively.
