木结构钢板螺栓连接节点承载力计算分析及试验研究

To facilitate engineering design of timber structures, the formulae to calculate the load-carrying capability of bolted connection with steel plates were derived and the methods to predict the lower bound and upper bound of the load-carrying capability in terms of bending moment of the bolted joints were proposed. Specimens of bolted joints with inserted steel plates were designed and manufactured. Tests of the joints under combined axial compression, shear and bending moment were conducted. It is found out that the averaged load-carrying capability of the joints under each loading case all falls in the range between the calculated lower and upper bounds of load-carrying capability, and is actually equal to the average value of the lower and upper bounds. The correctness and the feasibility of the formulae to calculate the load-carrying capability of the bolted connections with steel plates and the methods to predict the load-carrying capability of the bolted joints are thus validated, which can provide the reliable basis for the design.
