Fabricated steel structure based on self-resetting angle braces and energy dissipation coupling beams
The invention discloses a fabricated steel structure based on self-resetting angle braces and energy dissipation coupling beams. The fabricated steel structure comprises steel frame beams and columns, the self-resetting angle braces and the energy dissipation coupling beams; the self-resetting angle braces are connected in an area near beam-column joints through bolts; the energy dissipation coupling beams are connected between the two steel frame columns through bolts; the columns and a foundation are connected through foundation bolts; and a stiffening rib is arranged near each bolt on a steel frame. According to the fabricated steel structure, under the action of static force, anti-seismic components keep elastic; under the action of an earthquake, the energy dissipation coupling beams always absorb earthquake energy through plastic deformation; the self-resetting angle braces provide deformation recovery capability for the structure under small, medium and large earthquakes; under a huge earthquake, the energy dissipation coupling beams fully deform to dissipate energy, meanwhile, the self-resetting angle braces enter a strengthening stage, the resistance of the structure is improved by rapidly increasing the bearing capacity so as to avoid overall collapse of the structure, and under the action of the earthquake, the structure is recovered to the initial position by the self-resetting angle braces while the earthquake energy is effectively dissipated.
本发明公开了一种基于自复位隅撑和消能连梁的装配式钢结构，包括钢框架梁、柱、自复位隅撑和消能连梁，自复位隅撑通过螺栓连接在梁柱节点附近区域内，消能连梁通过螺栓连接在两根钢框架柱之间，柱和基础之间通过地脚螺栓连接，钢框架上每个螺栓附近均布置有加劲肋。本装配式钢结构在静力作用下，抗震构件保持弹性；在地震作用下，消能连梁始终通过塑性变形吸收地震能量；自复位隅撑在小、中、大震下为结构提供恢复变形的能力；在巨震下，消能连梁充分变形耗散能量，同时，自复位隅撑进入强化阶段，通过迅速增加的承载力以提升结构的抗力从而避免结构的整体倒塌，并且在地震作用下，在有效耗散地震能量的同时，自复位隅撑将结构恢复到初始位置。
