Post-earthquake replaceable steel frame beam-column connecting joint with multi-stage fortification and double energy consumption
The invention discloses a post-earthquake replaceable steel frame beam-column connecting joint with multi-stage fortification and dual energy consumption. The post-earthquake replaceable steel frame beam-column connecting joint comprises a steel column (1), a bracket (2), a steel beam (3), a web connecting plate (41), a lower flange connecting plate and a mild steel damper (6). The bracket is arranged on the steel column, and a bracket upper flange (21) is butted and fixed with a steel beam upper flange (31); the bracket web (22) is slidably connected with the steel beam web (32) through a web connecting plate, and the bracket lower flange (23) is slidably connected with the steel beam lower flange (33) through a lower flange connecting plate; when the bracket is in butt joint with the steel beam, the mild steel damper is connected between the lower flange of the bracket and the lower flange of the steel beam in an inserted and meshed mode, and the mild steel damper is connected with the lower flange connecting plate in a sliding mode. It can be guaranteed that beam-column connecting joints are completely rigidly connected under the static working condition and the small earthquake effect, energy dissipation and shock absorption are achieved under the medium earthquake effect and the large earthquake effect, meanwhile, installation and post-earthquake repair are facilitated, and the clear height of the beam bottom is not occupied.
本发明公开了一种多级设防双重耗能的震后可更替式钢框架梁柱连接节点，包括钢柱(1)、牛腿(2)、钢梁(3)、腹板连接板(41)、下翼缘连接板和软钢阻尼器(6)；牛腿装在钢柱上，牛腿上翼缘(21)与钢梁上翼缘(31)对接固定；牛腿腹板(22)通过腹板连接板与钢梁腹板(32)可滑移式连接，牛腿下翼缘(23)通过下翼缘连接板与钢梁下翼缘(33)可滑移式连接；牛腿与钢梁对接时，软钢阻尼器插入式咬合连接在牛腿下翼缘与钢梁下翼缘之间，软钢阻尼器与下翼缘连接板可滑移式连接。本发明能保证梁柱连接节点在静力工况以及小震作用下为完全刚性连接，在中震和大震作用下耗能减震，同时便于安装和震后修复，且不占用梁底净高。
