Durabilità, in ambiente fortemente basico, delle fibre di PET provenienti dalla raccolta differenziata

2012

La sperimentazione esposta nella presente pubblicazione tratta dell’impiego di fibre di PET, ricavate dal semplice taglio di contenitori per bevande secondo un procedimento brevettato, nel rinforzo di calcestruzzi destinati anche a impieghi strutturali. Descrive le caratteristiche geometriche delle fibre e ne indaga la durabilità in condizioni severe che potrebbero presentarsi in un’applicazione pratica quale una pavimentazione esterna. A tal fine campioni costituiti da gruppi di fibre sono stati immersi per tredici giorni a 65°C in soluzioni a differente concentrazione di NaOH (0,103 M e 1,75 M). In particolare la soluzione a concentrazione 0,103 M di NaOH (pH=13) simula la basicità della …

Nuevos materiales moleculares multifuncionales conmutables con transición de espín

2022

Este trabajo de Tesis Doctoral se centra en la síntesis y caracterización de nuevos materiales moleculares conmutables basados en FeII, los cuales presentan el fenómeno de transición de espín (spin crossover, SCO). El objetivo principal de esta tesis doctoral ha sido el diseño y estudio de nuevos materiales multifuncionales de FeII que combinan el comportamiento SCO con otra propiedad físico-química de interés. La estrecha interrelación entre el fenómeno SCO y dicha propiedad ha sido seguida y estudiada por estudios magnéticos, cristalográficos y calorimétricos, entre otros. El capítulo 1 de esta tesis describe los conceptos teóricos más importantes del fenómeno SCO, donde los centros SCO e…

Przepis art. 299 Kodeksu spółek handlowych jako funkcja prawa o niewypłacalności

2022

Przepis art. 299 Kodeksu spółek handlowych nawiązuje do treści art. 298 Kodeksu handlowego. Polski ustawodawca model spółki z ograniczoną odpowiedzialnością generalnie oparł na regulacji niemieckiej. Niemniej z uwagi na częste przypadki nadużywania formy spółki kapitałowej wprowadził szczególną odpowiedzialność członków zarządu. Regulacja art. 299 Kodeksu spółek handlowych przez lata była przedmiotem ożywionej debaty nauko-wej i wielu orzeczeń sądowych. W niniejszym opracowaniu stawiana jest teza, że wskazana regulacja jest funkcją prawa upadłościowego. Konsekwencją tej tezy jest wskazanie na zakres odpowiedzialności członka zarządu spółki z ograniczoną odpowiedzialnością, który podej-mie o…

Flexural Behavior of Steel Fibrous Reinforced Concrete Deep Beams

2012

Experimental research was carried out regarding the flexural behavior of deep beams cast with plain and fibrous concrete with hooked steel fibers, and subjected to monotonic vertical loads. Four deep fiber-reinforced concrete beams were cast. Two of them were made of plain concrete with main and web steel reinforcements (RC), and two were made of hooked steel fiber-reinforced concrete (SFRC) with main steel reinforcements. The experimental results show the brittle behavior of reinforced deep RC members characterized by crushing of concrete struts and fracture of web steel bars. SFRC deep beams exhibit higher strength and, above all, ductility with respect to RC members due to the bridging a…

Experimental Investigation on Stiffness and Strength of Single-Lap Z-Pinned Joints in a Laminated CFRP Stress-Ribbon Strip

2016

Carbon fiber-reinforced polymer (carbon-polymer) is an advanced lightweight composite material with high strength and excellent resistance to corrosion and fatigue. Over the past decades, application of fiber-reinforced polymers has been spread from the aerospace to other branches of industry such as automobile and civil engineering. Unidirectional carbon-polymers have a high potential for replacing steel in tensile members. Recently, the first carbonpolymer stress-ribbon bridge has been constructed in Germany. The non-laminated strip-loop carbon-polymer thin strips were used as the load bearing components in this bridge. In comparison with the laminated components, the applied cables are c…

Procedure for Safety Assessment and BIM Modelling of an Historical Complex Structure through a Macroelement Approach: The Building “Molino-Pastificio…

2022

The structural assessment of existing historical structures is a complex task due to the inner main difficulty in making up reliable models for structural analysis, able to include mechanical and geometrical nonlinearities, existing damage, complex configurations and arrangements of materials. This task becomes more difficult in mixed RC-masonry structures, which structural modelling can be particularly tough due to the different connections and interactions between structural members and materials. This paper presents the case study of a multi-storey mixed Reinforced Concrete (RC)- masonry historical structure, namely the former mill “Molino-Pastificio Soresi” building, located in Partinic…
