Streszczenie:

The brittleness of concrete has always been a safety and economic issue of great concern. The low tensile strength of concrete is the cause of its intrinsic brittle nature. This is critical considering the amount of concrete used for the construction of highways, buildings, and other facilities. The mechanical properties of concrete must be improved to provide upgraded construction. Crack resistant and durable concrete has always been a major goal for engineers. Many approaches have been tried to make concrete a better construction material. Fiber reinforcement is an approach which has been sh

The aim of this thesis was to investigate the difference between containerboard materials strength and stiffness properties in tension and compression, how the mechanisms behind compressive and tensile properties are affected by the relative humidity of the ambient air and how the relative humidity affects the compressive response of the fibre network. These properties are used to predict the lifetime performance of corrugated boxes and to prevent early collapses of the boxes and thereby waste or harm of the transported goods inside.

There are approximately 4000 railway bridges in Sweden managed by the Swedish Administration of Transport (Trafikverket), of which a common construction type is the reinforced concrete (RC) trough bridge, which is a structure that consists of a slab carried by two longitudinal main beams which transfer loads towards the supports. A substantial amount of the RC trough bridge population is approaching the end of their service lives which consequently implies that the replacement of some of these bridges can be expected in the near future. Extending their service lives can yield positive effects

Natural fibre composites (NFCs), which are polymers reinforced with cellulosic bast fibres, have the potential to be applied into a range of building products. They are seen as an alternative to glass fibre reinforced plastics (GFRP) in some applications, because of natural fibres (NF) relatively high strength and low density. Moreover, natural fibres have a set of beneficial traits, such as thermal insulation, thermal stability, biodegradability, and are inherently renewable. Those characteristics are of importance when NF are used as reinforcements in polymer composites, but developments in

Ce travail porte sur l'étude de liens entre les propriétés mécaniques de comprimés modèles composés de billes de verre et les caractéristiques physico-chimiques des liants, constitués de sucres et préparés sous forme de sirops. Le procédé de fabrication consiste en une méthode modifiée de compression humide. Deux paramètres de formulation ont été testés : le taux de saturation en sirop et sa concentration massique. Nous en avons tiré une variable unique qui est la fraction massique de sucre ajoutée aux billes de verre. Ces paramètres se sont avérés essentiels dans la maîtrise de la tenue mécan

Desiccation-induced soil cracking is of significant interest in several engineering disciplines, which include geotechnical and geoenvironmental engineering, mining engineering, and agriculture engineering. The hydraulic, mechanical, thermal and other physico-chemical properties of unsaturated soils can be predominantly influenced due to cracks. Reliable information of these properties is required for the rational design and maintenance of earth structures taking account of the influence the soil-atmosphere interactions (e.g., for expansive soil slopes, earth dams, and embankments).

The tensile strength or the negative pressure required to induce cavitation in a pure liquid has been a puzzling subject. On one hand, the classical nucleation theory has met great success in predicting the nucleation rates of superheated liquids. On the other hand, most of reported experimental values of the tensile strength for different liquids are far below the prediction from the classical nucleation theory. In this study, homogeneous nucleation in liquid nitrogen and its tensile strength have been investigated. In order to carry out the measurement of the tensile strength of liquid nitro

Assunto cada vez mais em pauta nos foros nacionais e internacionais e nas comunidades ao redor do mundo, a questão ambiental tem sido a grande responsável pela geração de produtos novos. A construção de obras de infraestrutura é um dos maiores consumidores de recursos naturais, gerando uma enorme quantidade de resíduos, acaba também por ser um setor causador do impacto ambiental. Tais resíduos, se descartados de maneira incorreta geram problemas ambientais, em contraponto o descarte em aterros sanitários tem um custo bastante elevado.

It is well known that most liquids exhibit a tensile strength which is much smaller in magnitude than the tensile strength predicted by homogeneous nucleation theory. This lack of agreement is usually attributed to the difficulty of preparing liquid samples free from foreign gases which act as heterogeneous nucleation sites. Liquid helium occupies a unique place among liquids for tensile strength measurements because all foreign gases are frozen out at liquid helium temperatures. Furthermore, superfluid 4He should fill all crevices on solid surfaces, eliminating the chance of heterogeneous nuc

The pervious concrete system and its corresponding strength are as important as its permeability characteristics. The strength of the system not only relies on the compressive strength of the pervious concrete but also on the strength of the soil beneath it for support. Previous studies indicate that pervious concrete has lower compressive strength capabilities than conventional concrete and will only support light traffic loadings. This thesis investigated prior studies on the compressive strength on pervious concrete as it relates to water-cement ratio, aggregate-cement ratio, aggregate size

Rock discontinuities are fundamentally important to most rock engineering projects but predicting or measuring their properties such as roughness, aperture, shape and extent (persistence) are fraught with difficulty. So far the solution of how to measure or predict persistence is poorly researched partly because the concept of how to investigate the extent of rock discontinuities within a rock mass seems intractable, by any economical methods. In the majority of engineering applications it is a fairly widespread practice to follow a conventional approach, assuming a 100% persistence value. How

When a tension steel plate is welded to a gusset steel plate and a tension load is transmitted to the gusset plate by longitudinal welds along both edges at the end of the tension plate, the shear lag factor (U) is used to determine the design tensile strength for the plate. The shear lag factor is determined from the American Institute of Steel Construction (AISC) Manual. The shear lag factor is selected from the table based on the length of the weld and the width of the steel plate that is in tension. The thickness of the plates, boundary condition of the gusset plate, the size and strength
