Novel post-earthquake damage-free multi-stage energy consumption self-resetting wood frame shear wall
The invention discloses a novel post-earthquake damage-free multi-stage energy consumption self-resetting wood frame shear wall which comprises an orthogonal laminated wood shear wall body connected to a concrete foundation through shape memory alloy bolts. The two sides of the orthogonal laminated wood shear wall are each connected with a wood frame column through a shape memory alloy bolt, a wood frame combined cross beam is connected between the tops of the two wood frame columns, and a set of S-shaped metal energy dissipation dampers are arranged between the wood frame combined cross beam and the orthogonal laminated wood shear wall. And a group of rigid polyurethane foam buffer blocks is arranged between each of the two sides of the cross-laminated wood shear wall and the wood frame column. Damping and energy dissipation are carried out by means of mild steel, shape memory alloy, springs, rigid polyurethane foam and the like, and then self-resetting of the structure is achieved by means of retraction of components and stored earthquake energy.
本发明公开了一种新型震后无损伤多阶段耗能的自复位木框架剪力墙，包括通过形状记忆合金螺栓连接在混凝土基础上的正交胶合木剪力墙，在所述混凝土基础上，位于所述正交胶合木剪力墙的两侧各通过形状记忆合金螺栓连接一个木框架柱，两根所述木框架柱的顶部之间连接有木框架组合横梁，所述木框架组合横梁与所述正交胶合木剪力墙之间设置有一组S形金属消能阻尼器，所述正交胶合木剪力墙的两侧与所述木框架柱之间各设置有一组刚性聚氨酯泡沫缓冲块。本发明利用软钢、形状记忆合金、弹簧、刚性聚氨酯泡沫等多种手段进行减震耗能，之后利用构件的回缩以及被储存的地震能量实现结构的自复位。
