Load-carrying capacity of axially-loaded RC members with circular openings

2012

Abstract Core drilling is today one of the most used technique among the group of partially destructive testing methods in reinforced concrete (RC) members. Even if the engineering practice provided to extract cores only in beams, taking samples from columns could be often necessary. In this case, the presence of the hole introduced a geometrical discontinuity in the member, creating a disturbed region. Consequently, compressive stresses will disperse in lateral direction as they have to avoid the drilled area. A bursting tensile force will develop, in orthogonal direction to the column axis, and if no sufficient reinforcement was arranged, a vertical crack will form, leading to the concret…

Advanced Strategies and Materials for Reinforcing Normal and Disturbed Regions in Brick Masonry Columns

2016

This work presents the results of an experimental investigation on the behavior of 42 solid clay brick masonry columns internally strengthened by fiber-reinforced polymer (FRP) fabrics or stainless steel grids placed in horizontal mortar joints. In some cases, every course, and in other cases, alternate courses were reinforced with steel grids, carbon, and basalt FRP fabrics. Monotonic compressive loading tests were carried out under concentric and eccentric loads. Eccentric tests were carried out by loading the specimens on a reduced area with respect to the entire cross section, producing a disturbed region (D-region). A detailed characterization of the constituent materials was made expe…

La transición en España: poder nacional y poder regional en UCD-Valencia, UCD-Castellón y UCD-Alicante (1976-1982)

2015

Estudiar el origen, evolución y crisis de la Unión de Centro Democrático (UCD) es fundamental para obtener algunas de las claves de la Transición española a la democracia (1976-1982). En esta tesis se analiza la historia de UCD interrelacionando documentación y testimonios de gestores de UCD-nacional, pero también de UCD-Valencia, UCD-Castellón y UCD-Alicante. Con un aporte documental sólido y una base bibliográfica que intercala trabajos procedentes de la Historia, la Ciencia Política y la Sociología, se hace especial hincapié en que UCD fue un partido político con una evolución clara hacia dos objetivos: consolidar la UCD como un partido de masas y transformar plenamente su entramado inst…
