Displacement Estimation of Structures With Flag‐Shaped Hysteresis Loops
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Time‐history analyses were conducted on single‐degree‐of‐freedom (SDOF) systems with flag‐shaped hysteresis loops using a far‐field ground motion suite to estimate peak displacements, Δp, and equivalent deformation cycles, Nc, associated with cumulative displacement demands.

Klyuchevskoy Volcano: new flank eruption named after G.S. Gorshkov, 2021 (Kamchatka)
Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2021 On February 18, 2021, a flank eruption started on the north-western slope of the Klyuchevskoy Volcano (Kamchatka, Russia). Cinder cone was formed at the altitude of 2 850 m above sea level, from which a lava flow was spreading north-west.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Masonry infills in reinforced concrete (RC) frames are highly vulnerable to seismic damage, often sustaining severe cracking even under moderate ground motion, which in turn leads to considerable economic losses and safety risks. To address this issue, this study experimentally evaluates the effectiveness of two innovative rubber‐based joints ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Earthquakes often occur in clusters (foreshocks, mainshocks, and aftershocks) and can lead to cumulative structural damage. Many studies have extended traditional performance‐based earthquake engineering (PBEE) to account for damage accumulation in multiple mainshock‐aftershock (MS‐AS) sequences using Markov chain processes and state‐dependent
