摘要
为探究足尺单板层积材(LVL)在木结构建筑中的强度,测试3种尺寸试样的抗压强度和2种尺寸试样的抗拉强度。结果表明:试件长度对其顺纹抗拉强度有显著尺寸效应,随着试样长度的增加,LVL的抗拉强度减小;试样长度和截面尺寸对其顺纹抗压强度亦有显著尺寸效应,随着长度及截面尺寸增加,抗压强度减小。
In order to analyze the mechanical properties of laminated veneer lumber （LVL） used in wood construction, the authors selected LVL specimens with different dimensions to test tension strength and compression strength parallel to grain. The results showed that the tension strength of the samples was influenced by the length, and the tension strength decreased as length increased. Moreover, the compression strength of the samples was also significantly affected by the length and the transverse dimensions, which decreased as the length and the transverse dimensions increased
