摘要

竹子具有生长周期短、力学性能好、节能环保等优点。它被认为是一种具有巨大发展潜力和应用前景的新型建筑材料。然而，目前对竹原材料设计值的研究还很缺乏。本研究通过对原竹材料进行拉伸试验，确定了原竹材料的抗拉强度设计值，并得到了原竹材料抗拉强度和弹性模量的统计值。确定了原竹材料抗拉强度的标准值和阻力不确定性统计参数。考虑不同的载荷组合和载荷效应比，得出了不同载荷组合下的可靠性指数与阻力分量系数的关系以及最佳阻力分量系数，并得出了原竹材料抗拉强度的设计值。

Design value of tensile strength of raw bamboo

Bamboo has the advantages of a short growth cycle, good mechanical properties, energy savings, and environmental protection. It is regarded as a new building material with great development potential and application prospects. However, current research on the design values of raw bamboo materials is lacking. In this study, the design value of tensile strength of raw bamboo material was determined by a tensile test of the raw bamboo material, and the statistical values of the tensile strength and elastic modulus of the raw bamboo material were obtained. The standard value and resistance uncertainty statistical parameters of the tensile strength of the raw bamboo material were determined. Considering different load combinations and load effect ratios, the relationship between the reliability index and the resistance component coefficient and the optimal resistance partial coefficient under different load combinations were obtained, and the design value of the tensile strength of the raw bamboo material was obtained.
