El factor más influyente en la reducción de la rigidez de las estructuras de hormigón armado se encuentra en la capacidad de deformación anelástica de los aceros utilizados en las armaduras, es decir, en su ductilidad. En esta tesis se aborda el análisis del comportamiento plástico de varios tipos de acero corrugado hasta rotura, estudiando en...

The use of stainless steel rebars to reinforce masonry structures has become established as an eminently efficient methodology. From among the numerous techniques available, bed-joint structural repointing and superficial reinforcement with rebars or meshes attached to surfaces have become widespread, thanks to the excellent results they have...

The use of stainless steel rebars in the repair of masonry structures is widespread and has traditionally produced excellent results. In these cases, rebars usually present diameters of below 8 mm covered with thin layers of mortar or grout. Research is necessary to characterise bonding under these particular conditions, hitherto unavailable....

The calculation of the true stress and strain values during the tensile test necking phase of smooth ductile metals specimens has been extensively pursued by several authors. A symmetrical neck profile, which leads to axial-symmetrical behaviour, is usually considered. In this study, the neck geometry of Temp-core ribbed bars, the most commonly...

Ajuste de los aceros corrugados ferríticos, austeníticos y austenoferríticos a los modelos de endureci-miento elastoplástico por deformación. Uno de los principales factores tenidos en cuenta en la fabricación de aceros estructurales es su comportamiento durante la fase elastoplástica o de endurecimiento por deformación. Normas neozelandesas y...

The typical distribution of steel used in developed countries, according to World Steel Association, attributes approximately 35% of total steel production in the world to the construction sector. Rebar steel consumption constitutes a significant proportion of that figure. More in-depth knowledge regarding the behaviour of steels used in the...

In steel, the knowledge beyond the yield strength elastic is of the utmost importance because of the large plastic strain that take place both at the time of the breakage and multiple conformation processes involving a stretch of material, such as rolling or extrusion. Beyond the manufacturing process, the trend nowadays is to the use of more...

Tensile behaviour of metals beyond the ultimate tensile strength (UTS) must be considered to calculate toughness or absorbed energy till fracture. Structural steels, designed to withstand earthquakes, are the typical material where post necking behaviour can be of paramount importance. This paper deals with the tensile stress-strain behaviour...

Ultra-fine blast-furnace slag binders have recently been introduced to repair masonry. The reduced particle diameter of these binders makes them especially suitable for use as grouts, since this characteristic enables these grouts to fill even the smallest voids. The current necessity and effectiveness of Finite Element Analysis in any process...
