Unreinforced masonry structures

Bulletin of the New Zealand Society for Earthquake Engineering, 1996
Unreinforced masonry is widely used in Australia as an architectural and structural material. Because of its high mass, lack of ductility and low tensile strength it is unsuitable for use in areas of high seismicity. However in countries of lower seismicity such as Australia it can be used provided it is designed, detailed and constructed correctly ...

Seismic Enhancement of Masonry‐Infilled Substandard Reinforced Concrete Frames Using Lightweight Steel Exoskeleton

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 603-623, March 2026.
ABSTRACT A significant portion of existing reinforced concrete (RC) structures in seismically active regions was constructed prior to the adoption of modern seismic design standards, leaving them highly susceptible to earthquake‐induced damage. The vulnerabilities of these structures, often exacerbated by material degradation, have been starkly ...

Parametric Study of Orthotropic Masonry Walls under Static and Dynamic Loading

Tehnički Glasnik
The paper presents a parametric study of unreinforced and confined masonry walls with orthotropic properties under in-plane static and dynamic loading. A previously developed FEM model was extended to simulate the behaviour of the orthotropic masonry and

Evaluating the Seismic Damage Dynamics of Buildings’ Vertical Growth in Lima, Peru

Earthquake Spectra, Volume 42, Issue 1, February 2026.
In Lima, as in many cities, most residential buildings grow vertically over their lifespan due to incremental construction. Multiple stories are added to buildings, often without structural retrofits or even without design. As a result, the seismic vulnerability of these buildings increases, requiring the government to create resilience policies that ...

Predicting Seismic Debris Distributions of Collapsed Unreinforced Masonry Structures Through Physics Engines and Machine Learning Algorithms

Earthquake Spectra, Volume 42, Issue 1, February 2026.
Unreinforced masonry (URM) structures are widespread worldwide, particularly in older urban districts. However, URM buildings—particularly those constructed before the introduction of modern building codes—are highly vulnerable to seismic hazard, and prone to experiencing local and/or global failures when subjected to significant horizontal shaking ...

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

Lateral strength force of URM structures based on a constitutive model for interface element

Latin American Journal of Solids and Structures
This paper presents the numerical implementation of a new proposed interface model for modeling the behavior of mortar joints in masonry walls. Its theoretical framework is fully based on the plasticity theory. The Von Mises criterion is used to simulate

Benchmark Dataset From Centrifuge Shake Table Tests of 3D‐Printed Unreinforced Masonry Structures for Seismic Model Validation

Earthquake Spectra, Volume 42, Issue 1, February 2026.
This data paper presents a comprehensive dataset derived from a series of 29 centrifuge shake table tests of 29 identical virgin small‐scale physical models of an unreinforced masonry (URM) structure. System‐level testing of full‐scale civil engineering structures under seismic loading is often prohibitively expensive and time‐consuming due to specimen

Shear Strengthening of Stone Masonry Walls Using Textile-Reinforced Sarooj Mortar

Buildings
Most historical buildings and structures in Oman were built using unreinforced stone masonry. These structures have deteriorated due to the aging of materials, environmental degradation, and lack of maintenance.
