Strength hierarchy provisions for transverse confinement systems of shell structural elements [PDF]

, 2019
Through-the-thickness (TT) confinement of masonry and concrete panels by composite or steel reinforcements, aiming at seismic retrofit of existing structures, has recently growth in popularity.

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 ...

Numerical Verification of Interaction between Masonry with Precast Reinforced Lintel Made of AAC and Reinforced Concrete Confining Elements

Applied Sciences, 2020
This paper describes results of numerical analyses of reinforced lintels made of autoclaved aerated concrete built into unconfined walls and walls confined with reinforced concrete. The combination of the Menétrey–Willam elastic-plastic failure criterion

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 ...

Damage Probability Matrices and Empirical Fragility Curves From Damage Data on Masonry Buildings After Sarpol-e-zahab and Bam Earthquakes of Iran

Frontiers in Built Environment, 2020
The weakness of tensile strength and high weight in masonry structures under the dynamic loads of earthquakes has always led to structural damage, financial losses, injuries, and deaths.

Preliminary study of masonry - RC hybrid structure behavior under earthquake loading [PDF]

, 2012
Low-rise confined masonry structures are widely used in earthquake-risked rural areas. Most of these structures fail in shear pattern under lateral earthquake loading. In this study, as an improvement for earthquake resistance and post-quake restoration,

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.

Experimental Behavior of Confined Masonry Walls Rehabilitated with Reinforced Mortar Jacketing Subjected to Cyclic Loading

Buildings, 2023
Results of an experimental program of 13 confined masonry walls rehabilitated with different techniques are presented. All specimens were built to full-scale with an aspect ratio (height to length) of 1. Vertical confining elements of one wall were built

The Impact of a Pre‐Existing Defect on Liability for Property Damage: Taylor v Jones

The Modern Law Review, EarlyView.
Taylor v Jones involved liability for causing damage to a building that had a pre‐existing defect. The defendant was in principle liable for the cost of repairing the damage. However, the Court of Appeal denied liability for the cost of repairing the pre‐existing defect even though such repair was necessary to restore the building to the state it would

Axial behaviors of confined and unconfined brick masonry pillars

Frontiers in Built Environment
Bricks are globally used in both load-bearing and non-load-bearing structures. In the rural areas of many countries, economic constraints are the primary reason for adopting brick masonry in load-bearing structures.
