Topology optimization and seismic collapse assessment of shape memory alloy (SMA)-braced frames: Effectiveness

Aydin HASSANZADEH; Saber MORADI

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 3,   Pages 281-301 doi: 10.1007/s11709-022-0807-3

Abstract: This paper presents a seismic topology optimization study of steel braced frames with shape memory alloyOptimal SMA-braced frames (SMA-BFs) with either Fe-based SMA or NiTi braces are determined in a performance-baseddistribution of lateral displacement over the frame height while being more cost-effective than NiTi bracedframes.In frames with Fe-based SMA braces, the SMA usage is reduced by up to 80%.

Frontiers of Structural and Civil Engineering 2011, Volume 5, Issue 3,   Pages 259-266 doi: 10.1007/s11709-011-0114-x

Abstract: A retrofit of an existing 11-story steel reinforced concrete frame that features the innovative use of post-tensioned rocking walls and shear steel dampers is presented. The main components of the retrofitting plan and important design considerations are described. The retrofitting system is expected to effectively control the deformation pattern of the existing structure and significantly reduce damage to the existing structure during major earthquakes.
