Seismic Retrofitting of Corner RC Beam-Column Joints with Floor Slab: Numerical Assessment of Hybrid and Composite Systems [PDF]

Numerical Methods in Civil Engineering
This paper presents a finite element investigation into the seismic performance and retrofitting of corner RC beam-column joints with an attached floor slab—a realistic detail often neglected in previous studies.

A Performance‐Based Earthquake Fatality Modeling Framework Using Collapse Volume Ratios

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Conventional earthquake fatality models are commonly implemented using a binary representation of building collapse, an assumption that overlooks severe failure modes and systematically underestimates fatalities. To address this limitation, this study advances the collapse volume ratio—a continuous metric quantifying the reduction of survivable space ...

Validation of Physics‐Based Simulated Accelerograms for Seismic Fragility Analyses of Italian RC Existing Building Types

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This article aims at exploring and validating the use of 3D physics‐based simulated ground motions as seismic input for the derivation of seismic fragility curves based on nonlinear dynamic numerical analyses. Fragility curves are computed for a set of pre‐code (i.e., designed only for vertical loads), reinforced concrete building types representative ...

Experimental Dataset From Full‐Scale Near‐Collapse Tests on Two‐Storey, Two‐Bay Masonry‐Infilled Reinforced Concrete Frames With Timber‐Based Reinforced Concrete‐Timber Panel Seismic Retrofit

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This study describes a dataset from an experimental campaign investigating the quasi‐static cyclic lateral response of two full‐scale, two‐storey, two‐bay reinforced concrete (RC) frames with masonry infills representative of mid‐20th century European construction practice.

SEISMIC RETROFIT OF HIGHWAY BRIDGES

Journal of JAEE, 2004
This paper presents the seismic retrofit practice of existing highway bridges in Japan. At first, the histories of the past seismic design codes, past seismic evaluation, and past seismic retrofit practices for highway bridges are described. Then the damage caused by the 1995 Hyogo-ken Nanbu Earthquake and the lessons learned from the earthquake are ...

From Warnings to Actions: Factors Influencing Response to Earthquake Early Warning—A Systematic Literature Review

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Earthquake early warning (EEW) systems offer critical seconds for protective actions, yet their effectiveness ultimately depends on human interpretation and response. This article presents a systematic literature review of factors shaping public behavior during earthquakes and in response to EEW alerts.

Pseudodynamic Testing of Buildings Retrofitted with External Steel Reinforced Concrete Frames to Increase Lateral Strength for Earthquake Damage Prevention

Shock and Vibration, 2020
In this study, a new technique for seismic retrofitting via the attachment of an “external steel reinforced concrete frame” (ESRCF) system was developed to strengthen medium-to-low-rise reinforced concrete (RC) buildings. Two methods (bolting and welding)

Seismic Performance of Substandard Reinforced Concrete Roof T-joints Retrofitted with Prestressed Steel Plates

International Journal of Concrete Structures and Materials
This study proposes an innovative and practical retrofitting method for reinforced concrete (RC) roof T-joints with substandard structural details. Retrofitting was performed by assembling steel plates with threaded rods on the roof T-joints, which have ...
