摘要：选取试样尺寸、螺栓直径等因素对重组竹销槽承压强度进行分析,评价NDS/LRFD和Eurocode5中销槽承压设计公式对重组竹销槽承压强度预测的适用性,分析2个加载方向试样的破坏形态。结果表明:试样尺寸在满足设计最小值的前提下,对销槽承压性能无显著影响,销槽承压强度值在104.40～169.77MPa范围内波动;2个加载方向的销槽承压强度从数值上看,随螺栓直径的增大呈下降的趋势;NDS/LRFD和Eurocode5对重组竹销槽承压强度的预测值偏小;加载方向的不同对试样的破坏形式影响较大。
The dowel-bearing property is very important in compression yield strength calculation of bolted connections and is a critical component of wood or bamboo connection design. In this paper, the dowel-bearing strength was studied based on dimension, bolt diameter as test parameters. The application of NDS/LRFD and Eurocode 5 in dowel-bearing strength prediction was assessed. Besides, the damage modes in two loading directions were analyzed. It showed no dimension effect on dowel-bearing strength which ranged between 104.40 MPa and 169.77 MPa in either direction, if the dimension reaches the minimum requirements. !The dowel-bearing strength test values showed a decreasing trend with the bolt diameter increasing. NDS/LRF and Eurocode 5 all under predicted the dowel-bearing strength of recombinant bamboo. The damage modes of the two loading direction samples were obviously different.
