국내산 낙엽송 소경각재의 허용응력 산출 = Allowable Stress Calculation of Domestic Japanese Larch Small Diameter Lumbers

다국어 초록 (Multilingual Abstract)

Sustainable energy consumption and increasing CO2 emissions stimulate Eco-friendly industry. Wood has positive various properties as alternative energy such as solar, wind and water. Wood provide lumber, pallet, paper, pulp and fuel through production process. Even Korea republic has 63.7% of forest rates, weather condition makes low forestry production capacity. For utilization of domestic small diameter log needs study mechanical properties. In this study, various properties tested on domestic Japanese Larch small diameter lumbers and make mechanical properties table for allowable stress calculation. Result of compressive test, allowable compressive stress is 13 MPa. Allowable bending stress is 12 MPa.
