摘　　要：Nail connection is widely used in engineering and construction fields.In this study,bamboo nail was proposed as a novel connector for timber assemblies.Penetration depth of bamboo nail into wood was predicted and tested.The influence of nail parameters(length,radius and ogive radius)on penetration depth were verified.For both tested and predicted results,the penetration depth of bamboo nail increased with the increasing length,radius or ogive radius.In addition,the effect of densification on penetration depth or mechanical properties was evaluated.1.12 g/cm^(3) was a critical density when densification was needed,and further increment of density would decrease the penetration depth of nail.The results of this study manifests that the proposed model is capable to predict the penetration depth of bamboo nail.These findings may provide new insight into efficiently utilization of bamboo resources.
