Reinforcement detail: Stress trajectory‐oriented corbel reinforcement

Structural Concrete, Volume 24, Issue 6, Page 6923-6932, December 2023., 2023
Abstract The article presents a novel design of concrete corbels, where horizontal and vertical stirrups are replaced by main reinforcement bars that are bent down into the corbel web, following the principal stress lines. A test series of three specimen pairs of fanned‐out and conventional reinforcement design, supported by finite element analysis ...

Triaxial shake table testing of an integrated low‐damage building system

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 10, Page 2983-3007, August 2023., 2023
Abstract Lessons from recent earthquakes have provided a tough reality check of the traditional seismic design approach and technologies, highlighting the urgent need for a paradigm shift of performance‐based design criteria and objectives toward low‐damage design philosophy and technologies for the whole building system.

Load‐bearing capacity of Gerber saddles in existing bridge girders by different levels of numerical analysis

Structural Concrete, Volume 24, Issue 1, Page 211-226, February 2023., 2023
Abstract This paper numerically investigates three typologies of Gerber saddle in existing ordinary and post‐tensioned girder concrete bridges. The main goals of this work concern the evaluation of the effective load‐bearing capacity of Gerber saddles, and the identification of weak points (i.e., lack of enough diagonal reinforcement, loss of ...
