Out-of-plane seismic response of stone masonry walls: experimental and analytical study of real piers [PDF]

, 2012
This paper presents the application of an existing simplified displacement-based procedure to the characterization of the nonlinear force-displacement relationship for the out-of-plane behaviour of unreinforced traditional masonry walls.

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 ...

New Zealand contributions to the global earthquake model’s earthquake consequences database (GEMECD) [PDF]

, 2015
The Global Earthquake Model’s (GEM) Earthquake Consequences Database (GEMECD) aims to develop, for the first time, a standardised framework for collecting and collating geocoded consequence data induced by primary and secondary seismic hazards to ...

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 ...

Selection of the Optimal Intensity Measure for Unreinforced Masonry Buildings Using Vulnerability-Based Metrics

Buildings
Selection of the optimal intensity measure is an important contribution to reducing the numerous uncertainties in seismic inputs within the context of performance-based earthquake engineering, especially for unreinforced masonry buildings that exhibit ...

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

Numerical Simulation of Unreinforced Masonry Buildings with Timber Diaphragms

Buildings, 2021
Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the effect of the connections between floors and walls is rarely discussed or explicitly modelled when simulating the response of such buildings.

Fragility curves and loss estimation for traditional timber-framed masonry buildings in Lefkas, Greece [PDF]

, 2015
The 2003 earthquake in the Greek island of Lefkas, has revived the interest for the local anti-seismic technique based on the use of timber-framed masonry, whose adequate performance during the earthquake revealed the merits of this rather sophisticated,
