Bond‐slip modeling for reinforced concrete beam‐column joints with plain reinforcement bars: Insights from numerical validation

Structural Concrete, EarlyView.
Abstract The previous seismic events indicated the vulnerability of old reinforced concrete (RC) structures against earthquakes due to the absence of seismic detailing and capacity design specifications in such buildings. In this context, beam‐column joints (BCJ) of the existing RC structures built before the 1970s have exhibited poor structural ...

Modeling of Structural Masonry

, 2023
Masonry is a composite material, and its behavior shows that its weaknesses lie in the minimum resistance of its components and the characteristics of the interfaces between them. Ceramic brick masonry has technological characteristics that make it suitable for housing and building functions. The bricks, of reduced dimensions and joined with mortars 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 ...

Modelling, analysis and testing of masonry structures

, 2005
In this thesis, masonry churches under horizontal actions are studied. Such structures feature strong seismic vulnerability, both because of the mechanical properties of the material and the particular configuration.

TRM‐to‐concrete interface bond without anchors: Combined experimental, analytical, and numerical modeling approach

Structural Concrete, EarlyView.
Abstract Textile reinforced mortar (TRM) systems have emerged as an effective alternative to conventional FRP strengthening solutions due to their compatibility with concrete substrates and favorable performance under adverse environmental conditions.

A F.E. UPPER BOUND LIMIT ANALYSIS MODEL FOR MASONRY CURVED AND 3D STRUCTURES, WITH AND WITHOUT FRPREINFORCEMENT

, 2010
The aim of this thesis is to propose a new efficient numerical tool, based on the kinematic theorem of limit analysis, for the study of masonry shell and 3D structures with or without FRP reinforcement. The approach consists of two steps.
