摘要

为有效控制强震后Y型偏心支撑钢框架结构的塑性残余变形

通过将Y型偏心支撑中耗能梁段的腹板更换为形状记忆金属（SMA）材料

提出了一种新型自复位SMA耗能梁段。使用ANSYS软件建立有限元模型分析得出

与传统耗能梁段相比

SMA耗能梁段具有旗帜型滞回曲线

承载力及延性无明显下降

可实现震后自复位功能。此外

还设计6组16个SMA耗能梁段试件

并进行了滞回性能分析。研究发现设计参数变化对SMA耗能梁段的自复位功能影响较小;腹板厚度及耗能梁段长度对SMA耗能梁段的承载力及初始刚度影响显著;翼缘厚度及宽度、翼缘材料及加劲肋间距对其承载力及初始刚度影响较小

但其后期承载力会出现一定程度的劣化。

Abstract

In order to reduce the post-earthquake residual displacement of Y-shape eccentrically braced steel frame structure

an innovative link beam with self-centering behavior was proposed.The web of this new link beam was fabricated using the shape memory alloy（SMA）material.The finite element model（FEM）of the SMA link beam was developed using ANSYS software.The hysteretic behavior of the SMA link beam was compared with the traditional link beam.The analytical results indicate that the SMA link beam obtains the flag-shaped hysteretic curve

lateral strength

and initial stiffness.The favorite self-centering behavior of the SMA link beam is also realized.Additionally

a total of sixteen SMA link beams were designed

and the hysteretic behavior was also analyzed and compared.The results show that these related design parameters have little influence on the self-centering behavior of SMA link beams.However

the web thickness and the length of link beam have significantly effects on the shear strength and initial stiffness of SMA link beam.The flange thickness

flange width

flange material

and the space of steel ribs produce slight effects on the shear strength and initial stiffness of SMA link beams except for the post-peak shear strength.
