A Study on the Compression Performance for Transmission Tower Feet Based on Innovative Clamp Elements
Based on the innovative reinforced technology for main members of transmission towers,a new connecting method of reinforced members at the tower foot is proposed,which can effectively avoid secondary damage to the original connection plate of main members at the tower foot,and the construction process can also be simplified.An experimental study on the eccentric compression behavior of the reinforced steel tower foot containing 2 groups of 6 full-scale specimens is conducted,and the failure mode,ultimate bearing capacity and stress distribution law of the reinforced tower foot are analyzed.The research results show that the local buckling of reinforced members are found on the main member other than the tower foot;compared with the original member,the ultimate bearing capacity of the reinforced members is increased about 46%;and the strain of the main material section develops rapidly during the experiment,while that of the reinforced material section develops slowly and is relatively small,and basically remains in the elastic stage.
