“…The response of the RVE under out-of-plane actions is obtained subdividing along the thickness the unit cell into several layers (40 subdivisions). A displacement driven approach is adopted, meaning that macroscopic curvature increments 11,22,33 are applied through suitable periodic boundary displacement increments. In this way, homogenized curves are approximated to define the nonlinear behaviour of the interfaces.…”

“…The interest of researchers regarding the dynamic analysis of masonry structures subjected to impacts has been growing, but experimental studies on the behaviour of these structures is still scarce [11]. Recognizing the importance to develop further studies on the field, numerical models play an important role.…”

“…A scientific-based intervention is less exposed to inadequate actions and thus in the evaluation of its safety, the numerical modelling is a valuable tool. Insomuch, it is mandatory to understand the behaviour of unreinforced masonry (URM) structures due to fast non-linear dynamic analyses [9][10][11][12]. The present paper addresses a simple two-step procedure within the scope of homogenization approach.…”

ABSTRACT:The challenge of protecting the nation against the attack of terrorism has raised the importance to explore the understanding of building materials against the explosion. Unlike most of the building materials, brick masonry materials offer relatively small resistance against blast loading. In this research, a brick masonry wall was exposed to varying blast load at different scaled distances. Six tests with different amounts of explosives at various distances were carried out. Pressure time history, acceleration time history and strain at specific location were measured. The parameters measured from experimental pressure time history and acceleration time history is compared with those determined by ConWep to establish the correlations between experimental determined records and ConWep values. The experimental results were also compared with some researchers. These correlations may assist in understanding the behaviour of masonry structures subjected to explosive loading. RESUMEN:Estudio experimental del comportamiento de una fábrica sometida a cargas explosivas.-Con el reto que supone proteger a la nación contra atentados terroristas se ha visto acrecentada la importancia de conocer el comportamiento de materiales de construcción cuando se someten a una carga explosiva. Al contrario de la mayoría de los materiales, las fábricas de ladrillo ofrecen poca resistencia a dichas cargas. En el presente trabajo, se estudió el comportamiento de una fábrica de ladrillo ante cargas explosivas colocadas a diferentes distancias del muro. Se realizaron seis pruebas con explosivos de potencias distintas y a diferentes distancias. Se trazaron las curvas presión-tiempo y aceleración-tiempo, midiéndose asimismo la deformación en un punto concreto. Los valores experimentales de las curvas presión-tiempo y aceleración-tiempo se compararon con los que se calcularon con la ayuda de la aplicación informática ConWep a fin de establecer las correlaciones entre ambos conjuntos de resultados. También se compararon los resultados experimentales obtenidos con los publicados por otros investigadores. Estas correlaciones podrían contribuir a mejorar el conocimiento del comportamiento de estructuras de fábrica sometidas a cargas explosivas.
