On the preservation of reinforced concrete architectural masterpieces: The challenges of the REcube project

Structural Concrete, EarlyView.
Abstract The preservation of reinforced concrete masterpieces from the 20th century poses a complex challenge. These structures often combine architectural, historical, and technological value, which standard engineering codes and conservation practices are not fully equipped to address. The Erasmus+ REcube project responded to this gap by promoting an

Seismic Behavior of Fatigue-Retrofitted Steel Frame Piers

Civil Engineering Dimension, 2013
Fatigue retrofit works have been conducted on severely fatigue damaged beam-to-column connections of existing steel frame bridge piers in Japan. It is clear that retrofit works provides additional stiffness but the significance on the seismic behavior of

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.

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 ...

Post‐earthquake field assessment and damage correlation of elevated reinforced concrete water tanks in Kahramanmaras/Elbistan, Türkiye

Structural Concrete, EarlyView.
Abstract This study evaluates the seismic performance of elevated reinforced concrete (RC) water tanks in the Elbistan region following the February 6, 2023 Kahramanmaras–Elbistan earthquakes. Field investigations, visual damage surveys, non‐destructive testing (ultrasonic pulse velocity—UPV), concrete compressive strength measurements, peak ground ...

Seismic evaluation of the southbound Stellenberg Interchange Bridge, B5593, in South Africa

Structural Concrete, EarlyView.
Abstract This study presents a nonlinear finite element assessment of the seismic vulnerability of Bridge B5593, located in the south‐western region of South Africa. Previous evaluations identified a high likelihood of column failure; however, these were based on linear material models incapable of capturing damage evolution.
