侧压竹是一种由竹片经胶合压制而成的竹集成材。为确定侧压竹集成材的强度指标,参照木材试验标准,对结构用侧压竹集成材试件进行了抗压强度、抗拉强度、抗弯强度、抗剪强度及弹性模量的试验实测,得到了侧压竹集成材清材的顺纹抗压强度、横纹弦向抗压强度、顺纹抗拉强度、横纹抗拉强度、抗拉弹性模量、抗弯强度、抗弯弹性模量、抗剪强度的平均值和标准值;以侧压竹集成材清材试件实测数据为基础,采用Pearson χ~2方法,验证了侧压竹集成材的各项强度实测值的概率分布均服从正态分布N(μ,σ~2);基于可靠度理论,考虑材料的天然缺陷、干燥缺陷、长期荷载等影响强度取值的因素,提出了考虑多因素影响的侧...

Side pressure laminated bamboo is made of bamboo pieces by gluing and pressing. In order to study its strength index, wood test standard was refer, the compression, tensile, flexural, shear, elastic modulus tests of side pressure laminated bamboo applied in structure were carried out. The average and standard values of longitudinal compressive strength, transverse tangential compressive strength, longitudinal tensile strength, transverse tensile strength, tensile modulus of elasticity, flexural strength, flexural modulus of elasticity and shear...
