Plastic Analysis and Testing of multidirectional SFRC flag slabs

This paper presents a theoretical and experimental study of multidirectional steel fibers reinforced concrete slabs (SFRC). The study is based on a real building application using SFRC flag slabs. For the evaluation of the slabs bearing capacity, plastic calculations are performed both at section and structure levels. The section analysis uses the perfect plastic stress-strain diagram, with reference to the values of the strength characteristics of SFRC based on previous jobs that used similar fibers and dosages. In the structure analysis the plastic yield lines method has been used. This method relates the section last bearing moment and the plastic collapse load. The experimental campaign has consisted of the testing of six 2 m. diameter circular shaped slabs prototypes, and has allowed to verify the reference resistance used in the calculations.

Aproximación al pintor Epifanio Díaz de Arcaute (1845-1910)

[ES]Con este trabajo pretendemos aproximarnos a la figura de Epifanio Díaz de Arcaute (1845-1910), un pintor no demasiado conocido y con una producción artística, por el momento, escasa. Su formación fue tradicional y académica, vinculada a la Academia de Bellas Artes de Vitoria, de la que terminó siendo profesor.
