Parallel strand bamboo (PSB) is an engineered bamboo product fabricated using crushed bamboo fiber bundles. Recently, this product finds applications in the civil engineering field. It is expected that the use of this composite will continue to grow because of its excellent mechanical performance, relatively low variability in material properties, and shape standardization. Modern bamboo structures made from PSB composites may be subjected to temperature variations during service. So far, however, there has been little discussion about the temperature-dependent creep. In this study, an investigation was carried out on the short-term behavior of the compressive property of PSB. A stress range of 8 to 64 MPa over a temperature range of 25°C to 75°C was considered in the 24-hour creep tests. In addition, Burgers model was adopted to describe the short-term creep behavior of PSB. Temperature and stress effects on the creep compliance of the Burgers model were also discussed.

温度和应力对平行股竹压缩蠕变行为的影响

平行束竹 (PSB) 是一种使用压碎的竹纤维束制造的工程竹制品。最近，该产品在土木工程领域得到了应用。由于其优异的机械性能、相对较低的材料特性可变性和形状标准化，预计这种复合材料的使用将继续增长。由 PSB 复合材料制成的现代竹结构在使用过程中可能会受到温度变化的影响。然而，到目前为止，关于温度相关蠕变的讨论很少。在这项研究中，对 PSB 压缩性能的短期行为进行了调查。在 24 小时蠕变试验中，考虑了 25°C 至 75°C 温度范围内 8 至 64 MPa 的应力范围。此外，采用 Burgers 模型来描述 PSB 的短期蠕变行为。还讨论了温度和应力对 Burgers 模型蠕变柔量的影响。
