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

open access: yesEarthquake 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 ...

Modern masonry structures and earthquakes : reinforced or unreinforced? [PDF]

open access: yes, 2013
The evolution of structural masonry is briefly reviewed, from old thrust line behavior to modern global behavior using shear walls. For modern structural masonry, the use of unreinforced, confined and reinforced masonry is addressed in seismic areas.

Traditional timber frame walls: mechanical behavior analysis and retrofitting [PDF]

open access: yes, 2015
Timber frame construction is characteristic of several historic city centres as well as of vernacular architecture in several countries around the world, either motivated by the availability of materials and construction traditions or by the need of ...

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

open access: yesEarthquake 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 ...

Quantifying the out-of-plane response of unreinforced masonry walls subjected to relative support motion

open access: yesFracture and Structural Integrity, 2019
TThe supports of out-of-plane loaded unreinforced masonry walls in buildings are subjected to a motion that is filtered and amplified by the building structure and, in some cases, can be significantly different from the ground motion.

Seismic Retrofitting of Mid-Rise Unreinforced Masonry Residential Buildings after the 2010 Kraljevo, Serbia Earthquake: A Case Study

open access: yesBuildings, 2023
There is a significant building stock of post-WWII low- and mid-rise unreinforced masonry (URM) buildings in Serbia and the region (former Yugoslavia).

Experimental Evaluation of Prototype Seismic Retrofits for Precast Concrete Hollow‐Core Floors

open access: yesEarthquake 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
