The invention discloses an assembled double-beam self-resetting anti-seismic steel frame. The steel frame comprises at least one structural unit, the structural unit comprises two frame columns, an upper I-shaped steel beam, a lower I-shaped steel beam, upper pin roll devices and lower pin roll devices, wherein the upper I-shaped steel beam and the lower I-shaped steel beam are arranged adjacently, the upper pin roll devices and the lower pin roll devices are arranged on the frame columns, and the two ends of the upper I-shaped steel beam are respectively connected with the frame columns through the upper pin roll devices; the two ends of the lower I-shaped steel beam are respectively connected with a lower frame column through the lower pin roll devices, a gap is reserved between the upper I-shaped steel beam and the lower I-shaped steel beam, the two ends of the upper I-shaped steel beam and the lower I-shaped steel beam are integrally connected with end portion limit devices, a pre-pulling rod is anchored between the end portion limit devices at the two ends, and web strengthening plates are respectively arranged at the two ends of the upper I-shaped steel beam and the lower I-shaped steel beam. According to the steel frame, it is effectively avoided that influences on the strength and rigidity of a self-resetting double-beam are caused by the problems of an inclined end plate, length errors and the like, floor slabs cannot be destroyed, and the generated financial loss after earthquakes can be effectively avoided.
Description
technical field [0001] The invention belongs to the field of civil engineering, and relates to an assembled double-girder self-resetting anti-seismic steel frame that can realize frictional energy consumption under earthquake action. Background technique [0002] The self-resetting steel frame structure is a new type of structural form that provides self-resetting force for the structure by tensioning pre-tensioned rods, which can effectively reduce the residual deformation of the structure after the structure is subjected to an earthquake. Under frequent earthquakes, the gap between the beam-column joints of the self-resetting steel frame structure does not open, similar to a moment-resistant frame, and its structural members remain elastic; under the action of moderate or large earthquakes, the self-resetting steel frame structure passes through the beam-column The gap is opened at the top and bottom of the node, so that the energy-dissipating components installed at the n...
