Midspan cut-off type replaceable steel coupling beam
The invention relates to a midspan cut-off type replaceable steel coupling beam, and belongs to the technical field of building energy dissipation and seismic mitigation. The midspan cut-off type replaceable steel coupling beam comprises flange force transmission plates (2), an energy dissipation plate (2), friction type high-strength bolts (3), pressure-bearing type high-strength bolts (4), I-steel beams (5), common bolts (6), connecting angles (7) and embedded connecting plates (8). The flange force transmission plates (1) and flanges of the I-steel beams (5) are connected through the pressure-bearing type high-strength bolts (4), the energy dissipation plate (2) is connected with webs of the I-steel beams (5) through the friction type high-strength bolts (3), and the contact surfaces of the energy dissipation plate (2) and the webs of the I-steel beams (5) are treated through red rust generation after sand (shot) blasting. The force transmission plates and the energy dissipation plate of the proper sizes are selected under the external force effect, the midspan cut-off type replaceable steel coupling beam is earlier to be in the plastic state compared with an overall structure, energy is dissipated, and the effect of flexible replacement after an earthquake is achieved.
