中文摘要：
木质材料的持续负载效应,对木结构构件的设计和安全使用至关重要。本文总结木质材料持续负载效应的研究进展,介绍国外木质材料持续负载效应测试和评价标准,分析GB 50005-2003《木结构设计规范》对持续负载影响系数的规定,提出应借鉴国外成果,加快国产木质材料持续负载影响研究以及相关标准制定工作的建议。
英文摘要：
Understanding wood behavior under load is important to safely and effectively use wood members in wood structures.This paper reviewed foreign research on the duration of load（DOL） effects on wood and wood-based products.The related foreign standards on testing DOL wood behavior were also summarized.The authors analyzed the differences between the foreign and Chinese DOL factors.They also recommend that more research on DOL effects should be performed to develop relative standards for Chinese wood and wood-based products.
