STUDY ON AXIAL COMPRESSIVE BEHAVIORS FOR WOOD COLUMNS REINFORCED WITH CFRP

摘要：

Wood columns reinforced with CFRP sheets were studied under axial compression. Properties of unreinforced and reinforced columns are analyzed such as failure modes,load-strain relationships of timber columns and CFRP sheets,the bearing capacity and its influences of strengthened columns. The results indicate that the failure modes are various and local failure is often occurred at the position with flaws. The compression strength of strengthened timber columns is higher than that of unreinforced columns with an amplitude at 10％-20％. Such factors as the compression strength of timber,flaws of timber columns,stress modes,enwrapping forms of CFRP sheets are influenced the bearing capacity of strengthened columns.
