Fabricated viscoelastic adjustable self-resetting support
The invention provides an assembly type viscoelastic adjustable self-resetting support which solves the problems that a building needs to be dismantled and the post-earthquake recovery capacity of the building is seriously affected due to the fact that a buckling restrained brace is large in post-earthquake plastic deformation, serious in damage and difficult to repair or too high in repair cost. When the support is pulled or pressed, the middle elastic reset piece is compressed to store elastic potential energy, and after stress is finished, the stored elastic potential energy provides self-reset capacity for the support, so that the support is restored to the original state. The SMA stranded wires in the upper row and the lower row are always in a stretched state, energy is consumed by means of hyperelasticity of the SMA stranded wires, and the SMA stranded wires recover to the original state due to the self-resetting performance of the SMA stranded wires after stress is finished. In the assembling process, the tension progress of the SMA stranded wires can be adjusted through the tension progress adjusting component, the prestress of the self-resetting capacity of the buckling restrained brace device can be adjusted in advance in the installing process, and the more suitable self-resetting capacity can be provided for the brace.
本发明提供了一种装配式粘弹性可调节自复位支撑，解决了屈曲约束支撑震后塑性变形大，损坏严重难以修复或修复成本过高，这就导致需要将建筑物拆除，严重影响建筑物的震后恢复能力的问题。本发明在受拉或受压时，中间的弹性复位件压缩储存弹性势能，当受力结束后，储存的弹性势能为其提供自复位能力使得支撑恢复原来的状态。上下两排的SMA绞线始终处于拉伸状态，利用SMA绞线的超弹性进行耗能，当受力结束后SMA绞线的自复位性能使其恢复到原来状态。在装配时，可以通过张进度调节构件调节SMA绞线的张进度，使屈曲约束支撑装置的自复位能力的预应力能够在安装时进行提前调节，可以为支撑提供更为适宜的自复位能力。
