Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Weak‐Story Mitigation and Drift Redistribution in Moment‐Resisting Frames Using Stepping Rocking Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study investigates the seismic response of moment‐resisting frames retrofitted with a stepping rocking wall, with emphasis on weak‐story mitigation and residual drift reduction under both ordinary and pulse‐like ground motions. Nonlinear response‐history analyses are conducted on 9‐story and 20‐story SAC Los Angeles frames.

Effects of Wall‐to‐Floor Interactions on Seismic Response of Platform‐Type CLT Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Platform‐type cross‐laminated timber (CLT) buildings feature discontinuous wall segments supported by CLT floors. In practice, CLT floors are often treated as rigid diaphragm, yet the wall‐to‐floor interactions (WFIs) associated with flexibility of floors remain insufficiently investigated during seismic performance assessment.
