RISClutching Inerter Damper for Multidegree-of-Freedom Base-Isolated Structures: A Numerical Study
Publisher: American Society of Civil Engineers
Abstract: Base isolation systems (BISs) are used to isolate equipment or structures from vibration sources; however, the reduction in transmitted loads with the BIS can come at the cost of large isolation layer displacements. The ...
Three-Element Vibration Absorber–Inerter for Passive Control of Single-Degree-of-Freedom Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a novel passive vibration control device, the three-element vibration absorber–inerter (TEVAI) is proposed. Inerter-based vibration absorbers, which utilize a mass that rotates due to relative translational ...
Active Confinement of Reinforced Concrete Bridge Columns Using Shape Memory Alloys
Publisher: American Society of Civil Engineers
Abstract: This paper presents experimental and analytical work conducted to explore the feasibility of using an innovative technique for seismic retrofitting of RC bridge columns using shape memory alloys (SMAs) spirals. The high ...
Design of BRBs for and Collapse Performance of Strongback Braced Frames with Varying BRB Configurations
Publisher: American Society of Civil Engineers
Abstract: AbstractStrongback braced frames (SBFs) are a relatively new structural system with potential
benefits to seismic performance, resilience, and design flexibility. Design of SBFs
involves selection of energy-dissipating ...
Track Nonlinear Energy Sink for Rapid Response Reduction in Building Structures
Publisher: American Society of Civil Engineers
Abstract: A new type of nonlinear energy sink (NES), termed a track NES, is proposed in this paper. The shape of the track over which the auxiliary mass moves determines the character of the nonlinear restoring force for the NES. ...
Evaluation of Methods of Design for Strongback Braced Frames
Publisher: American Society of Civil Engineers
Abstract: Strongback braced frames (SBFs) are a relatively new structural system intended to reduce structural damage during seismic events and improve resilience. SBFs combine buckling-restrained braces, which provide the primary ...
Realization of a Strongly Nonlinear Vibration-Mitigation Device Using Elastomeric Bumpers
Publisher: American Society of Civil Engineers
Abstract: Recent research has shown the viability of using nonlinear energy-sink (NES) devices for vibration mitigation in mechanical and structural systems. When attached to a primary structure, these lightweight passive devices ...
