SELF-RESETTING ENERGY-DISSIPATING STEEL SUPPORT HAVING SHAPE MEMORY ALLOY DAMPER
The present invention relates to the technical field of energy dissipation and shock absorption buildings, and particularly relates to a self-recovering energy dissipation support with a shape memory alloy damper. The self-recovering energy dissipation support includes a core shape memory alloy damper and cross-shaped steel columns, wherein the shape memory alloy damper is composed of two sets of inner and outer sleeves. A sliding groove is arranged between the inner sleeve and the outer sleeve, so that the inner sleeve and the outer sleeve can slide relative to each other along a track. The two sets of inner sleeves are connected through pre-stretched superelastic shape memory alloy ribs I. The inner sleeves and the outer sleeves are connected through pre-stretched superelastic shape memory alloy ribs II. An outer end plate of the shape memory alloy damper is connected with the cross-shaped steel columns. No matter whether the support is in a tensioned or stressed working state, the device enables the superelastic shape memory alloy ribs to be in the tensioned working state through relative sliding of the inner sleeves and the outer sleeves in the shape memory alloy ribs, thereby giving the support stable and excellent self-recovering and energy dissipation capacity, and effectively improving the anti-earthquake performance of buildings.
