摘要:

综述树种和材性变异、应力水平、温度、含水率等因素对木材蠕变的影响,介绍分析含水率稳定和变化条件下木材蠕变模拟预测等方面的研究进展情况。我国木材蠕变特别是木材的机械吸附蠕变研究尚缺乏系统性,应综合考虑不同的影响因素对木材蠕变进行充分研究,以建立不同条件下木材蠕变预测的模型,为国内木材蠕变研究及木结构建筑的安全和可靠性设计提供基础。

Abstract:

This article summarizes factors, such as tree species and wood property variation, stress level, temperature and humidity etc.,influencing creep behavior in wood material, and analyses the creep models under stable and variable conditions respectively. The research on creep especially on mechano-sorptive creep in China is not enough, the intensive study considering all creep affecting factors to establish creep models in wood should be strengthened urgently in China.

Key words: creep in wood, TTSP, mechano-sorptive creep, model
