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 ...

Physics‐Based Encoder‐Only Transformer for Structural Hysteresis Prediction and Dynamic Analysis

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Accurate modeling of structural hysteresis is a critical task for ensuring the safety of structures through reliable response predictions. However, conventional hysteresis models often struggle to represent diverse hysteresis characteristics observed in real‐world structures, as the manual selection of a model form may not assure validity and ...

A Parametric Computational Framework for Modeling and Seismic Design of Post‐Tensioned Mass Timber Rocking Walls

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Post‐tensioned cross‐laminated timber (PT‐CLT) rocking walls offer a compelling seismic system combining self‐centering behavior with energy dissipation. However, progress in their performance assessment and design has been limited by the lack of a comprehensive parametric modeling tool, as exists for steel or reinforced concrete systems. This

Structural Effects of Vertical Non‐Skeletal Elements (NSEs) With Rocking Mechanisms

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper introduces the structural effects provided by vertical non‐skeletal elements (NSEs), such as claddings and partitions, with vertical slotted holes at their supports to enable rocking as the frame undergoes significant lateral deformation.

Numerical Simulations of 5‐Story Building Using Wood Light‐Frame Shear Walls and Post‐Tensioned Cross‐Laminated Timber Rocking Wall Dual Systems

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study explores the seismic performance of a five‐story prototype building using different configurations of a dual lateral force‐resisting system (LFRS) combining post‐tensioned cross‐laminated timber rocking walls (PT‐CLT‐RW) with conventional wood light‐frame shear walls (LiFS).

Deteriorated Hysteresis Behavior of Reinforced Concrete Bridge Columns With Lap‐Spliced Circular Hoop Reinforcement

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Five lap‐spliced circular hoop (CH) concrete bridge columns, designed in accordance with the current Japanese bridge design code and Taiwan bridge design practice, were tested in this study to investigate the effects of longitudinal reinforcement and aspect ratios on deteriorated hysteresis behavior.

A Three‐Parameter Continuum Timoshenko Beam Framework for Evaluating Higher‐Mode Effects in High‐Rise Buildings With Rotational and Translational Base Flexibility

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Higher‐mode effects can significantly amplify seismic demands in high‐rise buildings, causing unintended damage over the building height. Engineered mechanisms are introduced at the base of these structures to mitigate higher‐mode effects. Existing continuum formulations for base‐flexible buildings commonly idealize the superstructure as a ...

A Practical Formulation for Seismic Damage Accumulation on Multiple Mainshock‐Aftershock Sequences Based on Disaggregation of the Mainshock Hazard

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

Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

Energy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.
