All-steel SMA energy dissipation self-resetting buckling-restrained energy dissipation supporting structure and construction method
The invention provides an all-steel SMA energy dissipation self-resetting buckling-restrained energy dissipation supporting structure and a construction method. The all-steel SMA energy dissipation self-resetting buckling-restrained energy dissipation supporting structure comprises an inner core square steel tube, wherein the two sides of the inner core square steel tube are each provided with an outer wrapping steel channel, each outer wrapping steel channel comprises a main plate and lug plates arranged on the two sides of the main plate, the main plates of the outer wrapping steel channels make contact with the surface of the inner core square steel tube in an attached mode, a pair of rigid rods is arranged on the surface of one side, far away from the inner core square steel tube, of each main plate wrapped with each channel steel, the rigid rods are perpendicular to the main plates, the distance between the pair of rigid rods is set, end plates are arranged at the two ends, corresponding to openings, of the inner core square steel tube, and SMA stranded wires are connected between the rigid rods and the end plates close to one side of the rigid rods. The supporting structure has the advantages that the SMA stranded wires with pretightening force are connected between the end plates and the rigid rods, the purpose of vibration energy dissipation is achieved through self-resetting of the SMA stranded wires, the lateral rigidity of a frame body connected with the supporting structure is increased, and the earthquake resistance of a building is improved.
本申请提供一种全钢SMA耗能自复位防屈曲耗能支撑结构及施工方法，包括内核方钢管，内核方钢管的两侧分别设置外包槽钢，外包槽钢包括主板以及设置在主板两侧的耳板，外包槽钢的主板与内核方钢管的表面贴合接触；外包槽钢的主板远离内核方钢管的一侧表面设置一对刚性杆，刚性杆与主板垂直设置，一对刚性杆之间距离设定间距；内核方钢管对应其开口的两端分别设置端板，刚性杆与靠近其一侧的端板之间连接有SMA绞线。本申请的有益效果是：通过在端板及刚性杆之间连接预紧力的SMA绞线，通过SMA绞线自复位达到震动耗能的目的，增加与之连接的框架主体的侧向刚度，提高建筑抗震性。
