Beam column energy dissipation joint
The invention discloses a beam column energy dissipation joint which comprises an H-shaped steel column, an H-shaped steel beam, an upper T-shaped connecting piece, a lower T-shaped connecting piece and a damper. The upper T-shaped connecting piece and the lower T-shaped connecting piece are vertically arranged on the outer side of a flange of the H-shaped steel column, and a steel beam mounting space is formed between the upper T-shaped connecting piece and the lower T-shaped connecting piece; the H-shaped steel beam is horizontally arranged on the side edge of the H-shaped steel column, and the beam end of the H-shaped steel beam is arranged in the steel beam mounting space; the damper is arranged between the lower flange of the H-shaped steel beam and the lower T-shaped connecting piece, the upper end of the damper is connected with the lower flange of the H-shaped steel beam, and the lower end of the damper is connected with the lower T-shaped connecting piece; when the joint is damaged, the maximum stress appears on the damper, and the damper plays a role in protecting the beam column; when bearing a low-cycle reciprocating load, a hysteretic curve is full, the surrounding area of a hysteretic loop is large, the energy dissipation performance is good, the post-earthquake repair cost is reduced, and the fortification goals of being not damaged in a small earthquake, capable of being repaired in a medium earthquake and not falling down in a large earthquake are achieved.
本发明公开了一种梁柱耗能节点，包括H型钢柱、H型钢梁、上T型连接件、下T型连接件及阻尼器；上T型连接件与下T型连接件上下设置在H型钢柱的翼缘外侧，在上T型连接件与下T型连接件之间设置有钢梁安装空间；H型钢梁水平设置在H型钢柱的侧边，且H型钢梁的梁端设置在钢梁安装空间内；阻尼器设置在H型钢梁的下翼缘与下T型连接件之间，阻尼器的上端与H型钢梁的下翼缘相连，阻尼器的下端与下T型连接件相连；本发明当节点破坏时，最大应力出现在阻尼器上，阻尼器起到保护梁柱的作用；在承受低周往复荷载时，滞回曲线饱满，滞回环包围面积大，具有良好的耗能性能，且减小震后修复成本，实现“小震不坏，中震可修，大震不倒”的设防目标。
