| Research Abstract |
In this study, the mechanical properties of bolted connections in the large section timber were investigated. The effects of resin filled up into bolt-hole clearances on the load- capacity of bolted connections under static cyclic tensile loading was investigated in the experiment and finite element analysis using "contact element" was performed to clarify the stress property of a large section. As a result of experimental investigation, it was cleared that filling up resin into bolt-hole clearances leads to a decrease in the number of bolts under the same design condition. It was also indicated from the results of finite element analysis that "contact element" is able to be applied to the analysis of bolted connection.
