Effects of probability model misspecification on the number of ground motions required for seismic performance assessment

Earthquake Spectra, Volume 40, Issue 4, Page 2888-2916, November 2024.
The number of ground motions used in nonlinear response history analysis (NRHA) determines the precision of the parameter estimates obtained in seismic performance assessments. While this issue has been extensively studied in the earthquake engineering literature, the relationship of probability model misspecification to parameter estimation ...

A Random Field Model of Multipoint Bouncing Loads and Its Applications

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
In existing load models, the crowd bouncing load is often simplified as a single‐point excitation; moreover, these models lack data support from crowd bouncing experiments. Inspired by the random field models widely adopted in seismic ground motion fields, a random field model for crowd bouncing loads was established in this research.

Evaluation and Performance Testing of Eccentric Rolling Isolation System

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
Seismic isolation has become a widely accepted method for the protection of structures and nonstructural components. However, this control strategy is unfavorable against near‐fault earthquakes, particularly those featuring velocity‐pulse effects.

A Novel Enhanced Torsional Eddy Current Damper for Fixed‐Axis Rotation Control of Rigid Bodies

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
The control of angular velocities in the fixed‐axis rotation of rigid bodies is crucial for ensuring the safety and functionality of civil structures and mechanical systems. In this research, a novel enhanced torsional eddy current damper (ETECD) is proposed to effectively control the angular velocities of rigid bodies within confined installation ...
