Mechanical characterization of adobe bricks in existing constructions in Aveiro Region, Portugal [PDF]
In Portugal it is common to find earth constructions all over the country, being predominant in the centre and south. In the past, earth was massified as a construction material, used with different typologies and applications.

Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation
ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...

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 ...

ABSTRACT Over recent decades, the collection of seismic data has improved the understanding of near‐fault ground motion effects, which involve both horizontal and vertical components. Among the most significant effects are fault‐normal directivity, which concentrates seismic energy into an intense, long‐period pulse, and fault‐parallel fling step ...

Earthquakes have caused, and will continue to cause, damage to the built environment, resulting in casualties, economic losses, and long‐term societal impacts. One approach to decreasing future losses is limiting the damage that buildings experience during an earthquake and speeding up their recovery by following the “build back better” principle.

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 ...

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
