Seismic analyses of a R/C building: study of a retrofitting solution [PDF]

open access: yes, 2000
The preliminary experimental results from the tests on a 4-storey R/C frame structure are presented and discussed. The full-scale model is representative of the common practice of 40~50 years ago in most south European countries.

Seismic Enhancement of Masonry‐Infilled Substandard Reinforced Concrete Frames Using Lightweight Steel Exoskeleton

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 603-623, March 2026.
ABSTRACT A significant portion of existing reinforced concrete (RC) structures in seismically active regions was constructed prior to the adoption of modern seismic design standards, leaving them highly susceptible to earthquake‐induced damage. The vulnerabilities of these structures, often exacerbated by material degradation, have been starkly ...

Numerical Analysis of Masonry-Infilled RC-CLT Panel Connections

open access: yesBuildings, 2022
CLT panels have been investigated for reinforcement of existing masonry-infilled RC framed buildings through the increase of the overall lateral stiffness of the structure, thus reducing the story drift demand.

The use of FRPs in seismic repair and retrofit: experimental verification [PDF]

open access: yes, 2001
The application of FRPs in the seismic repair and retrofit of structures is addressed. The results from a few tests on full-scale structures, repaired and/or retrofitted with composites, performed at the ELSA laboratory are presented and ...

Combined Vertical and Horizontal Components of Near‐Source Earthquakes and Impact on Base‐Isolated Structures

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 781-803, March 2026.
ABSTRACT Over recent decades, the collection of seismic data has improved the understanding of near‐fault ground motion effects, which involve both horizontal and vertical components. Among the most significant effects are fault‐normal directivity, which concentrates seismic energy into an intense, long‐period pulse, and fault‐parallel fling step ...

Experimental study on strengthened masonry infill walls as structural components for enhancing the lateral load resistance of reinforced concrete frame structures

open access: yesJournal of Engineering and Applied Science
Enhancing the lateral load resistance of existing reinforced concrete (RC) frame structures while preserving adequate ductility remains a persistent concern in lateral strengthening, particularly when masonry infill walls are present.

Evaluation of infill strut properties based on in-plane cyclic tests

open access: yesGrađevinar, 2013
In the nonlinear analysis of masonry infilled RC frame structures, simple strut models are often adopted to represent the masonry infill, particularly in the case of extensive parametric numerical studies.

Advanced Techniques for Pilotis RC Frames Seismic Retrofit: Performance Comparison for a Strategic Building Case Study

open access: yesBuildings, 2020
Pilotis buildings have widely spread out in developed countries since World War II onwards. From the structural point of view, Pilotis RC frames exhibit substantial lack in ductility capacity and shear resistance localized at the first floor, since they ...

Numerical model to account for the influence of infill masonry on the RC structures behaviour [PDF]

open access: yes, 2005
It is a common misconception considers that masonry infill walls in structural RC buildings can only increase the overall lateral load capacity, and, therefore, must always be considered beneficial to seismic performance.

Building Back Better Following the 2023 Kahramanmaraş Earthquake Sequence: Repair and Retrofit of Damaged Residential Reinforced Concrete High‐Rise Buildings

open access: yesEarthquake Spectra, Volume 42, Issue 1, February 2026.
Earthquakes have caused, and will continue to cause, damage to the built environment, resulting in casualties, economic losses, and long‐term societal impacts. One approach to decreasing future losses is limiting the damage that buildings experience during an earthquake and speeding up their recovery by following the “build back better” principle.
