竹集成材性能研究进展
摘要：竹集成材是由原竹经工业化加工而成，在物理性能上优越于传统木材、绿色环保方面优于混凝土、砌体等传统建筑材料的一种具有发展潜力的新型建筑材料。目前，对于竹集成材的研究仍不够成熟，多数研究主要针对材料的基本力学性能和构件轴心受压性能、抗弯性能等，对于竹集成材柱偏心受压性能的研究几乎没有。在实际结构工程中，极少有理想的轴心受压构件，即使是按轴心受压设计的构件，也会因偶然的横向荷载、支座条件不理想或施工制作的偏差等情况而出现附加弯矩。因此，研究竹集成材偏压构件基本力学性能显得十分有意义。

Research on properties of bamboo composite material
Abstract: Bamboo composite material is a new type of building material with potential for development, which is superior to traditional wood and green building materials, such as concrete and masonry, in physical properties. At present, the research on bamboo composite material is still not mature enough, most of the research mainly aims at the basic mechanical properties of materials and the axial compression performance of components, bending properties, etc., there is little research on the eccentric compression performance of bamboo composite column. In the actual structural engineering, there are very few ideal axial compression members, even the components designed according to the axial pressure, will also be due to accidental transverse load, support conditions are not ideal or the deviation of construction production and other situations and additional bending moment. Therefore, it is very meaningful to study the basic mechanical properties of the partial pressure member of Bamboo composite material.

竹材与水泥、钢材、粘土砖等传统建筑材料相比较，它在生长过程中可以改善自然环境[1]。竹材为生物有机体，是碳的储藏库，据资料统计，每公顷毛竹林年吸收二氧化碳约47吨，而且二氧化碳能固定存储于砍伐后的竹材。竹材加工所需的能耗低，又因其有机高分子聚合体结构和内部空腔结构使其具有天然良好的隔热性能，与此同时竹材废弃后还可以自然降解[2]。因此竹结构建筑材料的制造、使用、废弃直到再生利用的整个生命周期中具备与生态环境的协调共存性。因此，研究竹集成材偏压构件基本力学性能，合理地发展竹结构建筑有利于生态平衡和环境保护，具有重大而深远的意义[3]。
