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

, 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.

Validation of a simplified micromodel for analysis of infilled RC frames exposed to cyclic lateral loads [PDF]

, 2016
An RC frame structure with masonry infill walls (‘‘framed-masonry’’) exposed to lateral loads acts as a composite structure. Numerical simulation of framed-masonry is difficult and generally unreliable due to many difficulties and uncertainties in its ...

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

Earthquake 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.

Experimental Evaluation of Prototype Seismic Retrofits for Precast Concrete Hollow‐Core Floors

Earthquake Spectra, Volume 42, Issue 1, February 2026.
Existing hollow‐core floors are vulnerable to nonductile failure and potential collapse under earthquake loading. This study presents the development and experimental evaluation of novel comprehensive seismic retrofits for hollow‐core floors. These retrofits include a strongback‐type retrofit that provides an alternative gravity load path through steel

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

Journal 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

Građevinar, 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

Buildings, 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 ...

Robustness assessment of reinforced concrete structures for different failure scenarios

Structural Concrete, Volume 27, Issue 1, Page 279-313, February 2026.
Abstract This study describes the robustness assessment of 3D reinforced concrete structures analyzing the response of the 2D frames in different design configurations and failure scenarios. The structures are characterized by both frames with wide beams and seismic‐resistant frames with deep beams.
