Shape memory alloy reinforced joint for connecting steel frames of power transmission tower
The invention belongs to the technical field of power transmission tower steel frame connection, and particularly relates to a shape memory alloy reinforced joint for power transmission tower steel frame connection, which can improve the fatigue load and earthquake/wind load resistance of a power transmission tower. The joint is a K-shaped joint and comprises an L-shaped column, a first inclined support, a second inclined support, a square joint plate and a plurality of shape memory alloy springs, and a frame of a K-shaped structure is formed. The shape memory alloy reinforced node has the capability of reducing the shape of the node, can reduce the fatigue response of the structural node under the action of reciprocating load, can dissipate the energy of earthquake and other structural vibration, and can restore the original shape through heating after the vibration load so as to maintain the constraining force; and meanwhile, deformation of bolt connection under the action of fatigue load is relieved, so that the structure has disaster resistance and self-repairing capacity, and the capacity of the steel frame structure for resisting wind load, earthquake load and other vibrations or impacts is improved.
本发明属于输电塔钢框架连接技术领域，具体涉及一种用于输电塔钢框架连接的形状记忆合金加强节点，可以提高输电塔抵抗疲劳荷载和地震/风荷载的能力。该节点为K型节点，包括L型柱、第一斜支撑、第二斜支撑、方形节点板和数条形状记忆合金弹簧，形成K型结构的框架。该形状记忆合金加强节点具备节点形状的还原能力，能够在往复荷载作用下减轻结构节点的疲劳响应，同时可以耗散地震和其他结构振动的能量，同时在振动荷载过后可以通过加热恢复原有的形状以保持约束力，同时减轻螺栓连接受到疲劳荷载作用下的变形，从而使得结构具有抵抗灾害和自修复能力，提高钢框架结构抵抗风荷载、地震荷载以及其他震动或冲击的能力。
