Impact assessment of earthquake early warning systems in Central America

Earthquake Spectra, Volume 41, Issue 4, Page 3094-3122, November 2025.
Earthquake Early Warning (EEW) systems aim to alert users in advance of imminent shaking, enabling them to take action. In collaboration with local seismic agencies, the Swiss Seismological Service (SED), has developed national EEW systems across Central America.

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.

Seismic Fragility Assessment of a Multi‐Span Masonry Arch Bridge Using a Discontinuum Modeling Approach

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 13, Page 3320-3340, 25 October 2025.
ABSTRACT This paper investigates the seismic performance of a multi‐span masonry arch bridge using an advanced modeling approach based on the Distinct Element Method. Located in Italy and constructed of regular stone masonry, the bridge features three consecutive arch vaults with similar geometry.

Performance of historical ferrocement specimens subjected to corrosive environments

Structural Concrete, Volume 26, Issue 5, Page 5785-5806, October 2025.
Abstract Ferrocement is a type of thin wall‐reinforced concrete composed of hydraulic cement mortar reinforced with several layers of steel wire mesh. The material is used as a low‐cost construction and retrofit solution and allows the creation of very thin elements.

Seismic Analysis of Unreinforced Masonry Walls

IDRiM Journal, 2017
The Alpine-Himalayan belt which covers the entire Himalayan range of India is the second most active seismic belt in the world. In the Himalayan range, the Indian plate is in an on-going collision with the Eurasian plate. The consequent interlocking between the two plates causes a release of accumulated strain at several faults in this collision zone ...

Probabilistic Simulation of Crack Propagation in Masonry Walls Using a Grain‐Based Energy Accumulation Model

ce/papers, Volume 8, Issue 3-4, Page 308-315, September 2025.
Abstract Unreinforced masonry (URM) buildings constitute an important portion of the European building stock, where metal injection anchors are widely utilized for seismic retrofitting. While crack propagation in URM walls is extensively studied, the interaction between these cracks and structural anchors remains an underexplored area of research. This
