摘要
阐述了国外木结构钉节点的握钉力研究现状。根据不同的钉杆形状,介绍了普通圆钢钉、螺钉、麻花钉三种常见钉形的握钉力特性,从握钉力计算公式、时间及含水率变化造成的松驰效应、表面涂层等强度影响因素以及结构用板材握钉力性能等五个方面分析了握钉力的研究发展,并对我国握钉力研究提出了建议。
This paper focuses on the nail withdrawal strength of the nailed joint in wood construction. An introduction is made about the withdrawal strength performance of three kinds of nail, such as nail, annularly threaded nail, helically threaded nail. The empirical equations relate to design value of withdrawal strengthe strength are also presented, Several important modification factors to the strength are discussed. Finally the future study about the nail withdrawal strength in China is proposed.
