Abstract

In transmission towers,ordinary galvanized bolts are widely used to connect angles,the connection properties determine the slippage at the nodes.The node connections are assumed to be rigid or hinge in traditional analysis and design of transmission tower,which make the status different from the real towers,A large number of experiments of the real towers suggested that the results of the calculation have a great difference with the experiments.In order to reduce the effect of bolted slip,the study put forward using an oblong bolt hole and arrangement of the hole .Imitating the tension process of the bolted connections by ANSYS simulation and present the influence of the connection slippage when the included angle between length direction oblongs and axis direction of angle changing and the pre-tightening force is different.Through the study we found that:the angle of the length direction of oblong bolted hole and the axis of the angle is larger,the pre-tightening force of the bolts is stronger,the bolted connection slip is smaller.
