Mechanical Properties of Zelkova Serrata Makino in Accelerated Weathering Test

This study was carried out to analyze the effects on mechanical properties of deterio-rated wood member by outdoor condition. The surface color, mechanical properties and struc-tural stability of traditional wooden structures, exposed in water and UV, could be changeable. For the purpose, accelerated weathering test based on outdoor condition was carried out. The weathering time levels were composed 0, 500, 1000, 1,500 and 2,000 hours and mechanical properties were evaluated on each specimen according to weathering time level. Bending proper-ties were decreased on weathering but recovered after 1,000 hours. Fatigue and impact strength were decreased to 1,000 hours and did not changed since then. Abrasion resistance was mini-mized in 1,000 hours. This results could be utilized for effectively stability management of tra-ditional wooden structures and members.
