| Abstract: | A series of beam specimens made of poplar LVL reinforced with CFRP sheets during their production process have been tested and studied. According to the testing results, the optimum beam section model has been selected, and the ultimate load bearing capacity and stiffness of reinforced beams have been enhanced obviously. The axial compression tests of the poplar LVL Columns Strengthened with CFRP sheet hoops have been carried out. The best column cross section model has been selected. The test results indicate that the CFRP hoops could enhance the ultimate capacity and improve ductility of the poplar LVL Columns obviously. |
