桉木制结构复合材PSL柱的静动态弹性模量
Jianzhu Cailiao Xuebao/Journal of Building Materials(2013)
Abstract
以新型桉木制结构复合材PSL柱为试验对象,进行了应力波无损动态力学性能测试和足尺顺纹受压静态力学性能测试,探讨了PSL柱动、静态弹性模量之间的关系,分析了应力波沿PSL柱斜对角向的传播机理,建立了PSL柱斜对角向动态弹性模量的简化计算模型.结果表明:PSL柱纵向动态弹性模量与宽度方向、厚度方向、斜对角向动态弹性模量的比值分别为11.4,41.9,1.7左右;PSL柱纵向动态弹性模量约为纵向静态弹性模量的1.46倍;受压损伤后PSL柱纵向和斜对角向动态弹性模量均为相应未损伤动态弹性模量的0.84倍左右.PSL柱斜对角向动态弹性模量主要取决于应力波沿纵向、宽度方向、厚度方向传播的距离分量及各方向动态弹性模量的大小.
