摘要:
利用形状记忆合金材料(SMA)在相变伪弹性阶段的工作原理与力学性能,建立其在荷载和温度等因素作用下的本构模型;针对桥梁结构在外界条件激励作用下的受力特性,制作成形状记忆合金与橡胶复合桥梁支座,形成新的结构隔震装置.该装置具有自复位功能,可以改变桥梁结构中普通橡胶支座变形过大,不能恢复的缺陷,避免桥梁结构过早地出现病害.为SMA-橡胶桥梁复合支座的深入研究和广泛应用提供了理论基础
Abstract:
With the working principle and mechanical properties of shape memory alloy(SMA)in the pseudo-elastic state, the constitutive model is established considering the role of the external load and temperature. According to the force characteristics of the bridge structure under external incentive, The SMA-rubber bridge bearing which forms a new structure isolation device is made. This device has self-reset function and changes the bridge structure of defects where the deformation of the normal rubber bearing are too large and can not be restored. In this way, the bridge structure diseases can be avoided as early as possible. Meanwhile the analysis and research of the paper provides a theoretical basis for the depth research and extensive application of SMA-rubber bearing
