Energy dissipation type beam column joint
The energy dissipation type beam column joint comprises a steel column and a steel beam, the steel beam comprises a middle beam section and a short beam section used for being connected with the steel column in a welded mode, a gap is formed between the middle beam section and the short beam section, and a web plate of the middle beam section and a web plate of the short beam section are connected through a rotating friction energy dissipation damper. The flange plate of the middle beam section and the flange plate of the short beam section are connected through a connecting plate and/or a damper. The short beam sections and the middle beam sections are connected through the rotating friction energy dissipation dampers, under the small earthquake effect, beam column joints do not rotate, and only elastic deformation occurs at the joints. Under the action of a strong earthquake, the beam column joint rotates, rotating friction force is formed on a friction interface of the rotating friction energy dissipation damper, then earthquake energy is dissipated, a main beam column component in the beam column joint basically keeps elasticity, the anti-seismic performance under the strong earthquake is improved, and damage to the beam column joint is effectively reduced.
本发明公开了一种消能型梁柱节点，包括钢柱和钢梁，钢梁包括中间梁段和用于与钢柱焊接连接的短梁段，中间梁段和短梁段之间设有空隙，中间梁段的腹板和短梁段的腹板通过转动摩擦耗能阻尼器连接，中间梁段的翼缘板和短梁段的翼缘板通过连接板和/或阻尼器连接。短梁段和中间梁段通过转动摩擦耗能阻尼器连接，在较小的地震作用下，梁柱节点不发生转动，节点处仅发生弹性变形；在强震作用下，梁柱节点发生转动，转动摩擦耗能阻尼器的摩擦界面形成转动摩擦力，进而耗散地震能量，使梁柱节点内的主体梁柱构件基本保持弹性，提高了强震下的抗震性能，有效地降低了梁柱节点的损伤。
