Searching for materials to provide proper housing with less emission and low energy becomes an urgent demand with the ever-growing population. Bamboo has gained a reputation as an ecofriendly, highly renewable source of material. Parallel Strand Bamboo (PSB) is a new biocomposite made of bamboo strips which has superiority performances than wood products. It has attracted considerable interests as a sustainable alternative for more traditional building materials. But the mechanical performance study of PSB as construction materials is still inadequate. Also, the structural behavior of PSB is not quite understood as conventional construction materials, which results in the difficulties to predict the performances of PSB structural members. To achieve this purpose, 4-point bending experiments for PSB beams were carried out. The flexural performances, mode of failure in bending, and the damage mechanism of PSB beams were investigated in this paper.
随着人口的不断增长，寻找能提供排放更少、能耗更低的合适住房的材料成为一项紧迫需求。竹子已被誉为一种生态友好、高度可再生的材料来源。平行束状竹材（PSB）是一种由竹条制成的新型生物复合材料，其性能优于木制品。作为更传统建筑材料的可持续替代品，它已引起了相当大的关注。但PSB作为建筑材料的力学性能研究仍不充分。此外，PSB的结构性能并不像传统建筑材料那样为人所熟知，这导致难以预测PSB结构构件的性能。为实现这一目的，对PSB梁进行了四点弯曲试验。本文研究了PSB梁的抗弯性能、弯曲破坏模式及损伤机理。
