The purposes of this study was to investigate the effects of the configuration of the lamina on the engineering and fire performance of glulam made from Japanese cedar, Taiwania, Douglas-fir, and Southern pine lumber. First of all, two kinds of visually graded criterions, CNS 14630 and CNS14631, were applied to grade selected laminaes.

中文摘要本研究乃针对集成元之配置与设计进行集成材制造，探讨构造集成材之工程性能与火灾性状，以非破坏检测技术评估省产之柳杉、台湾杉等中小径木以及国外广泛用於集成材之花旗松与南方松等集成元之抗弯性质，建立其强度相关性。

After standard fire exposure test, the bending properties of glulam decreased with the fire exposure time increasing. The values of MOE and MOR decreased respectively from 4.1 GPa to 2.5-3.8 GPa and 48.2 MPa to 27.1-36.6 MPa for China fir glulam, from 5.3 GPa to 3.7-4.6 GPa and 54.8 MPa to 23.0-39.4 MPa for Japanese cedar glulam, from 5.3 GPa to 3.4-4.7 GPa and 51.4 MPa to 21.8-38.6 MPa for Taiwania glulam, from 7.7 GPa to 6.6- 6.9 GPa and 62.7 MPa to 33.2-40.8 MPa for Douglas-fir glulam, from 6.0 GPa to 4.4-5.3 GPa and 58.9 MPa to 26.4-42.1 MPa for Southern pine glulam.

经燃烧试验后，集成材之力学性质上，集成材之抗弯强度会随燃烧时间之增加而降低，其中，杉木集成材之MOE值由4.1 GPa降至2.5 - 3.8 GPa，MOR值由48.2 MPa降至27.1 - 36.6 MPa；柳杉集成材之MOE值由5.3 GPa降至3.7 - 4.6 GPa，MOR值由54.8 MPa降至23.0 - 39.4 MPa；台湾杉集成材之MOE值由5.3 GPa降至3.4 - 4.7 GPa，MOR值由51.4 MPa降至21.8 - 38.6 MPa；花旗松集成材之MOE值由7.7 GPa降至6.6 - 6.9 GPa，MOR值由62.7 MPa降至33.2 - 40.8 MPa；南方松集成材之MOE值由6.0 GPa降至4.4 - 5.3 GPa，MOR值由58.9 MPa降至26.4 - 42.1 MPa。
