Abstract: This paper introduces a retrofit design procedure for reinforced concrete (RC) frame buildings using alternative steel bracing systems based on the simple lateral mechanism analysis (SLaMA). Employing a displacement-based ...

Abstract: This study presents a novel modal parameter identification method enabling approximation of the mode shapes of linear systems using white-noise or earthquake inputs. The majority of well-established existing system ...

Abstract: A shake-table test of a 2-story full-scale low-damage concrete wall building was conducted on the multifunctional shake-table array at Tongji University to validate the system-level dynamic response of this type of building. ...

Abstract: Despite their good performance in terms of their design objectives, many modern code-prescriptive buildings built in Christchurch, New Zealand, had to be razed after the 2010–2011 Canterbury earthquakes because repairs ...

Abstract: Semiactive devices offer the opportunity to customize the device response, and thus to customize the overall structural hysteretic response. However, they are actively controlled and thus entail a significant addition of ...

Abstract: Existing welded steel moment frames are designed to tolerate substantial yielding and plastic rotation under earthquake loads. This sacrificial design approach can lead to permanent, and often irreparable damage when ...

Abstract: An experimental and computational study of an 80-percent scale precast concrete 3D beam-column joint subassembly designed with high force-to-volume (HF2V) dampers and damage-protected rocking connections is presented. A ...
