Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Study on seismic isolation system for long-period ground motion
Nihon Kikai Gakkai ronbunshu, 2015 In this paper, the authors have developed a new type of horizontal seismic isolation system which has large effect of vibration isolation for ordinary earthquakes and suppresses the resonance of the isolation system due to long-period ground motions ...

An SSI‐Informed Design for Tuned Mass Dampers With Small‐to‐Large Mass Ratios
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Tuned Mass Dampers (TMDs) are used to mitigate structural vibrations induced by seismic or wind excitation, by tuning the device to the system's dominant resonant frequencies. However, the TMD effectiveness can be undermined by soil‐structure interaction, which can lead to elongation of the vibration periods and to combined translational ...

EngAlthough conceptually simple, the application of seismic isolation can pose dangerous pitfalls. It is based on decoupling the dynamic response of a structure from the ground motion by inserting isolation devices at its base.
