The invention discloses a bent shear-type eccentric support energy-dissipating beam and a bent shear-type eccentric support structure and belongs to the technical field of steel frame support structures. The bent shear-type eccentric support energy-dissipating beam comprises an upper flange, a lower flange, a web and first stiffeners; the upper flange and the lower flange are parallel to each other; the web is perpendicular to the first stiffeners; the web and the first stiffeners are connected with the bottom of the upper flange and the top of the lower flange at the same time, wherein the web is provided with at least two through holes distributed along the length of the web and not penetrating the web; the upper flange is narrower that of a non-dissipating beam, and the lower flange isnarrower than that of the non-dissipating beam. The web is provided with the non-communicated through holes, and therefore, after the ends of the beam experience bending plastic deformation, the middle of the web may continue to experience shear plastic deformation. Therefore, the beam can dissipate seismic energy through bending plastic deformation and can also dissipate seismic energy through shear plastic deformation, energy-dissipating effect is improved, and aseismic performance is improved.
Description
technical field [0001] The invention relates to the technical field of steel frame support structures, in particular to a bending-shear type eccentrically supported energy-dissipating beam and a bending-shear type eccentrically supported structure. Background technique [0002] In high-intensity earthquake areas, curved eccentric support structures can be set in steel structures to enhance the seismic performance of buildings. During an earthquake, the curved eccentrically braced structure undergoes local plastic deformation to dissipate the seismic energy and prevent the building from collapsing. Common curved eccentrically braced structures include: energy-dissipating beams, non-energy-dissipating beams, braced beams, and frame columns. Wherein, the non-energy-dissipative beam and the energy-dissipating beam are arranged in parallel, and the ends of the two are connected; the support beam is connected to the bottom surface of the non-energy-dissipating beam; the frame col...
