Steel pipe inclined strut welding joint structure bearing large eccentric fatigue load
The invention relates to a steel tube diagonal bracing welding joint structure bearing large eccentric fatigue load, which comprises a steel tube, a joint plate and filled concrete, and the steel tube can be a square steel tube, a rectangular steel tube and a round steel tube. The section of the steel pipe is divided into two cavities by a middle steel partition plate, concrete is filled in the cavity on the compression side, and the gusset plate is connected with the concrete by arranging holes and penetrating ribs. Long-strip-shaped grooves are formed in the tension sides and the compression sides of the steel pipes and the middle steel partition plates, so that the gusset plates can be inserted into the long-strip-shaped grooves and are welded with the long-strip-shaped grooves, round holes are formed in the ends of the long-strip-shaped grooves in the tension side steel pipes, and the compression side steel pipes and the ends of the gusset plates are welded in a surrounding mode. According to the steel pipe inclined strut welding joint structure, the stress concentration and the fatigue stress amplitude of welding details on the tension side can be reduced, the fatigue strength of welding details on the compression side is improved, and the fatigue life of the steel pipe inclined strut welding joint under the action of the large eccentric fatigue load is prolonged on the whole.
本发明涉及了一种受大偏心疲劳荷载的钢管斜撑焊接节点结构，包括钢管，节点板，内填混凝土，其中钢管可采用方钢管、长方形钢管和圆钢管。钢管截面由中间钢隔板分为两个腔室，受压侧腔室中有内填混凝土，节点板通过设置孔洞并穿筋与混凝土连接。钢管的受拉侧、受压侧及中间钢隔板上开长条形槽，使得节点板能够插入其中并与之焊接，受拉侧钢管在长条形槽的端部开圆孔，受压侧钢管与节点板端部进行围焊。本发明提供的钢管斜撑焊接节点结构能够降低受拉侧焊接细节的应力集中和疲劳应力幅值，提高受压侧焊接细节的疲劳强度，总体提升了大偏心疲劳荷载作用下钢管斜撑焊接节点的疲劳寿命。
