EVALUATION OF EARTHQUAKE RESPONSE OF WOOD FRAME WITH DIAGONAL BRACE FASTENED BY NEW BRACE FASTENER

摘要

A new type brace fastener which fastens the end of a diagonal wood brace to the end of column is developed for Post and Beam construction wooden houses. Since the brace fastener contains high damping rubber, it absorbs a displacement between the end of a wood brace and a column, damage of wood around wood screws is able to be prevented. On shake table test of a wood frame with a wood brace fastened by the new brace fasteners, the new brace fastener showed higher seismic performance in comparison with normal brace fastener especially under large earthquake motion. Moreover, by means of earthquake response analysis, it was confirmed that the new brace fastener showed good seismic performance under several earthquake motions.
