Abstract

One of the most important indicators for using wooden materials as a building material is safety stress (SS). Site index is also an essential criterion for construction materials. This research was planned with the aim to reveal the relationship between safety stress and site index classes (I, II, III) of red pine wood, which is an important tree species of Turkey and the Mediterranean basin. Also, the safety coefficient was calculated. The safety stress tests for compression, bending, and tensile, tensile perpendicular to fibers, cleavage, and shearing strengths were calculated as 9.2, 9.7, 8.9, 0.35, 0.10, and 1.4 N/mm2, respectively. The statistical analyses indicated that the site index difference had a significant effect on the safety stress in red pine wood as mentioned above. Again, the safety coefficient was calculated as 5.27 for red pine wood. In addition, it was determined that the safety stress values of red pine wood provided the desired lower limit values according to the standard (TS 647 and EN 1995-1-1), excluding class I. As a result of the regression and correlation analyses, the presence of a moderately increasing linear relationship (R2 values equal to 0.41-0.68) was found between the density and safety stress values for all site indexes.
按场地指标等级划分红松木材的安全应力
使用木质材料作为建筑材料最重要的指标之一是安全应力(SS)。场地指标也是建筑材料的重要标准。红松是土耳其和地中海盆地的重要树种,本研究旨在揭示红松木材的安全应力与立地指数等级(I、II、III)的关系。并计算了安全系数。压缩、弯曲和拉伸、垂直于纤维的拉伸、解理和剪切强度的安全应力测试分别计算为9.2、9.7、8.9、0.35、0.10和1.4 N/mm2。统计分析表明,上述立地指数差异对红松木材的安全应力有显著影响。同样,计算出红松木材的安全系数为5.27。此外,确定红松木材的安全应力值提供了标准(TS 647和EN 1995-1-1)所需的下限值,不包括i类。回归和相关分析的结果发现,密度与所有场地指标的安全应力值之间存在适度增加的线性关系(R2值为0.41-0.68)。
