Two-stage energy consumption replaceable steel beam column joint
The invention designs a two-stage energy consumption replaceable steel beam column joint, which belongs to the technical field of building structure vibration control, and comprises a steel column upper cantilever section, a steel beam, a web friction hinge and a flange connecting plate. The friction hinge comprises an L-shaped connecting plate, a T-shaped connecting plate and a friction pad, the L-shaped connecting plate, the T-shaped connecting plate and the friction pad are connected through a pin shaft and a bolt, a stiffening device is arranged on the outer side of the L-shaped connecting plate, the friction hinge is provided with a bolt hole and a through hole for placing the pin shaft in the length direction, and the friction pad is arranged between the L-shaped connecting plate and the T-shaped connecting plate; the flange connecting plate is formed by arranging C-shaped energy dissipation thin plates and rectangular energy dissipation thin plates on the flange end plates in parallel at equal intervals. In the energy dissipation process of the joint, energy dissipation is achieved by means of rotating friction of the friction pads in the web friction hinges and yield of the energy dissipation thin plates in the flange connecting plates, the stiffening devices are arranged on the outer sides of the web friction hinges, and pre-tightening force is applied to fixing bolts of the stiffening devices, so that it is guaranteed that the friction pads in the friction hinges are evenly pressed, and the energy dissipation capacity of the joint is controlled and adjusted.
本公开设计一种双级耗能可更换钢梁柱节点，属于建筑结构振动控制技术领域，该耗能节点包括钢柱上悬臂段、钢梁、腹板摩擦铰以及翼缘连接板。摩擦铰包括L型连接板、T型连接板以及摩擦垫通过销轴和螺栓连接，且L型连接板外侧设有加劲装置，摩擦铰沿长度方向设有螺栓孔以及放置销轴的通孔，且摩擦垫设置在L型连接板和T型连接板之间；翼缘连接板由C型耗能薄板、矩形耗能薄板平行等间距于翼缘端板布置组成。该节点耗能过程中依靠腹板摩擦铰中摩擦垫的转动摩擦以及翼缘连接板中耗能薄板屈服耗能，并通过在腹板摩擦铰外侧设置加劲装置以及在其固定螺栓上施加预紧力来保证摩擦铰中摩擦垫的受压均匀从而控制调节节点的耗能能力。
