Development and Validation of a Seismic Design Method for Anchored Retaining Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Retaining walls with multiple anchor levels are widely used as permanent excavation support systems for the construction of linear infrastructures. Yet, their seismic behaviour remains largely unexplored, and current design approaches rely on conventional procedures that do not adequately reflect the actual dynamic response of these systems ...

Three‐Dimensional Analytical Model of a Podium Structure With Rocking Columns of Square Cross Section

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Allowing structural systems to uplift and rock during seismic excitation has emerged as an effective and inherently self‑centering form of seismic isolation. This paper develops a computationally efficient 3D analytical model suitable for the understanding of the behavior of rocking bridges.

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.

Seismic Performance of Reduced‐Strength Steel MRFs With SMA‐Based Superelastic Friction Dampers: An Experimental Investigation

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Shape memory alloys (SMAs) exhibit excellent self‐centering capability due to their stress‐induced phase transformation, making them highly suitable for applications in resilient infrastructure. This study investigates the seismic performance of reduced‐strength moment‐resisting frames (MRFs) equipped with SMA‐based superelastic friction ...

Enhancing the Seismic Resilience of Masonry‐Infilled RC Structures Using Rubber Joints: Full‐Scale 3D Shaking Table Tests

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 ...

Direction‐Aware Period Prediction for Seismic Risk Assessment and Application to an Urban Tall Building Portfolio in China

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Reliable estimation of the principal periods is essential for regional seismic risk assessment (RSRA) of urban building portfolios. For tall buildings, however, existing period‐prediction formulas are constrained by the lack of representative data, while building translational azimuths are neglected despite their importance for regional ...
