基于形状记忆合金的木框架节点设计

基于形状记忆合金的特性,自主设计了一种形状记忆合金木框架节点,包括木梁、木柱及梁端耗能型钢 , 其主要特点是采用形状记忆合金制成的螺栓 I、螺栓Ⅱ进行连接,能大幅度提高节点的耗能能力、耐久性能及耐火性能,并能实现变形后整体结构的自动复位,进而改善节点自恢复能力差的缺陷,具有构造简单、实用性强、加固效果显著等优点。Abstract: Based on the characteristics of shape memory alloy, a wooden frame node, including wood beam, wooden column and beam end. Its main features are the bolt I and bolts made of shape memory alloy, can greatly improve energy consumption, durability and fire resistance, and realize automatic reset of the overall structure after deformation, and improve the defects of poor self-recovery, with the advantages of simple structure, strong practicability and significant reinforcement effect.
