Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1270-1291, May 2026.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.

Behavior of Long‐Slotted Perforated Steel Plate Fuses in Timber Brace End Connections

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1247-1269, May 2026.
ABSTRACT Steel perforated plate fuses have emerged as a promising solution for mass timber seismic force‐resisting systems, offering tunable energy dissipation mechanisms, such as flexural and shear yielding, through geometric adjustments. This study examines the cyclic performance of perforated steel plate fuses employed in timber braced frames, with ...

Assessing Post‐Earthquake Emergency Healthcare Accessibility Considering Damage to Hospital Buildings and Transportation Infrastructure

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This article presents a framework for performing a regional assessment of the accessibility of emergency healthcare facilities after a major earthquake. Accessibility is assessed by applying the enhanced two‐step floating catchment area method to a regional road network, implemented in ArcGIS.

Vertical‐Component Seismic Response and System Identification of a 52‐Story High‐Rise Building Using Earthquake Data

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This study investigates the vertical dynamic response of a 52‐story high‐rise building in downtown Los Angeles using small‐magnitude earthquake data recorded by the Community Seismic Network. While seismic design traditionally emphasizes horizontal ground motion, vertical accelerations can have a significant impact on tall structures, leading to ...

User Acceptance and Perceptions of Earthquake Early Warning Systems as a Function of Information Type: The Case of Postearthquake Nepal

Earthquake Spectra, Volume 42, Issue 2, May 2026.
What drives user perceptions and acceptance of earthquake early warning systems (EEWS) as an emerging technology? Do distinct types of transparency into EEWS affect users’ perceptions of the system's usefulness and desirability differently? To address these questions, we focus on Nepal, an earthquake‐prone country with no active public EEWS ...

Designing of a new seismic base isolation system

Journal of Materials and Engineering Structures, 2019
The design of a new base isolation system is proposed in this research with the objective that the system does not transmit any force to the structure under horizontal loading. The structure must remain operational and steady. Before investigating the dynamics problem of the base isolation system, the isolator components of the model can be solved ...

Achieving Functionality Targets for Seismically Isolated Steel Buildings Using Gaussian Process Modeling

Earthquake Spectra, Volume 42, Issue 2, May 2026.
As seismic design paradigms shift toward functional recovery, there is a need for efficient methods to achieve desired decision variables (DVs), such as probability of replacement, repair cost, and downtime of the building, for seismically isolated buildings.

Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 926-946, 10 April 2026.
ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...
