The basic mechanic performance of glue laminated lumber(GLL) reinforced with glass fiber reinforced plastic(GFRP) for structural materials was studied.The differences of mechanic performance of the GLL reinforced with GFRP and the common GLL were compared by the test,and the quantitative influence of reinforcement ratio and arrangement pattern of GFRP on the mechanic performance was investigated.The test results show that the static bending strength of GLL increases with the increasing of GFRP reinforcement ratio,and the reasonable arrangem...
