WT-section-stiffened steel panel damper

A steel panel damper for reinforcing a building structure, the steel panel damper being arranged between a first member and a second member of the building structure along a first direction, the steel panel damper comprising:

• a first elastic segment being connected to the first member of the building structure, and including a first main board, two first flanges and two first sideboards, wherein the first flanges are perpendicular to the first main board and disposed on both sides of the first main board, wherein the first sideboards are symmetrically disposed on both sides of the first main board, and wherein two opposite sides of each of the first flanges are respectively connected the first main board and one of the first sideboards;
• a second elastic segment being connected to the second member of the building structure, and including a second main board, two second flanges and two second sideboards, wherein the second flanges are perpendicular to the second main board and disposed on both sides of the second main board, and wherein the second sideboards are symmetrically disposed on both sides of the second main board, and wherein two opposite sides of each of the second flanges are respectively connected the second main board and one of the second sideboards;
• an energy dissipation segment being disposed between the first elastic segment and the second elastic segment, and including a web, two energy dissipation flanges and at least one stiffener, wherein the two energy dissipation flanges are perpendicular to the web and are disposed on both sides of the web, and wherein the at least one stiffener is disposed on at least one surface of the web and is perpendicular to the web;
• a first end plate being disposed between the first elastic segment and the energy dissipation segment, perpendicularly connected to the first main board, the first sideboards, the first flanges, the energy dissipation flanges and the web;
• wherein a height of each of the first sideboards is substantially equal to a height of the first main board, and two ends of the first end plate extend in a direction perpendicular to the first direction and across the first flanges and the energy dissipation flanges so as to directly connect to the first sideboards;
• and
• a second end plate being disposed between the second elastic segment and the energy dissipation segment, perpendicularly connected to the second main board, the second sideboards, the second flanges, the energy dissipation flanges and the web;
• wherein a height of each of the second sideboards is substantially equal to a height of the second main board, and two ends of the second end plate extend in the direction perpendicular to the first direction and across the second flanges and the energy dissipation flanges so as to directly connect to the second sideboards;
• wherein a cross-sectional area perpendicular to the first direction of the first elastic segment or the second elastic segment is greater than that of the energy dissipation segment.
