STRENGTH PERFORMANCE EVALUATION OF MOMENT RESISTANCE FOR CYLINDRICAL-LVL COLUMN USING GFRP REINFORCED WOODEN PIN

초록

In this study, Moment resistance performance of column-beam joints using cylindrical laminated veneer lumber (LVL) column and glulam beam were evaluated. Two types of jointing methods - Type-A, in which the beam is put on the end side of column and Type-B, in which the beam is inserted into column - were applied. As a result of Type A, Moment resistance of the cylindrical-LVL column jointed with drift pins was shown to be 67 % higher than that of the larch log column jointed with drift pins. The larch log column jointed with GFRP Plate reinforced wooden pins was shown to be 14 % higher than that jointed with drift pins. In Type-B joint, the rotational stiffness of two specimens were 139.4 kN.m/rad. (Non-reinforced specimen) and 272.2 kN.m/rad. (reinforced specimen), respectively, and reinforced specimen was 95 % higher than Non-reinforced specimen. Based on this result it was assured that glass fiber reinforcement is able to reinforce the column.
