Abstract:

The doctoral thesis deals with the analysis of the dapped-end beam detail, in terms of theoretical modelling and practical design using the strut-and-tie method as well as experimental verification of the bearing capacity and the behaviour of the detail under load by means of load tests and subsequent numerical nonlinear analysis. A summary of known structural and static designs explored in the literature has been presented. In addition, the strut-and-tie method has been introduced as an appropriate tool for a consistent design of the detail, element or the whole structure. The theoretical bas

Abstract:

The strut-and-tie method (STM) is a simple and conservative method for designing concrete structures, especially deep beams. This method expresses complicated stress patterns as a simple truss or kinematic model made up of compression elements (struts), tension elements (ties), and the joints between elements (nodes). STM is based on lowerbound plasticity theorem, so using it properly will lead to a conservative design. Although the concepts of STM have been around in concrete design since the late 19th century, STM was first introduced in AASHTO LRFD in 1994 and ACI 318-02 in 2002. ACI 318 de

Abstract:

The major part of the work presented in this thesis is an investigation of the strut and tie method for designing 2-D in-plane, reinforced concrete structures. Two important issues relating to this method are addressed. Firstly, the issue of visualising an appropriate strut and tie model is dealt with. In many situations it may be difficult to visualise an appropriate model for a given structural system. Here, a convenient method of visualising strut and tie models is presented. Using elastic finite element analysis, low stressed parts of a structure are removed in a step by step process until

Abstract:

Deep beams have traditionally been calculated through experiments and estimations. The purpose of the Strut-and-Tie method is to design a truss with struts, ties and nodes and to calculate these. The method is by Eurocode 2 recommended to use for deep beams and the result will always be on the safer side because the actual capacity will always be equal to or greater than the truss. The purpose of the study is to create a step by step method description on how to use the method and then apply it in a deep beam for a five-story building.

The use of Cross-Laminated Timber products has increased in recent years with a range of structural applications including CLT tall buildings and folded structures. As CLT is used in more innovative structural applications the need for specific methods of design and analysis are apparent.

Abstract:

Construction practices are constantly evolving in order to adapt to physical locations and economic conditions. These adaptations may result in more cost-effective designs, but may also come at a cost of strength. In masonry shear walls, it is becoming more common to reduce the amount of grouting from every cell to only those with reinforcement, a practice known as partial-grouting. Partially-grouted masonry responds differently and in a more complex matter to lateral loads as compared to fully-grouted masonry. The response is made even more complex by wall discontinuities in the form of openi

Abstract:

Precast/Prestressed concrete girders are commonly used in bridge construction in the United States. The application and diffusion of the prestress force in a pretensioned girder causes a vertical tension force to develop near the end of the beam. Field surveys of the beam ends of pretensioned bridge girders indicate that many of the PCBT beams used in the Commonwealth of Virginia develop cracks within the anchorage zone region. The lengths and widths of these cracks range from acceptable to poor and in need of repair. Field observations also indicate deeper cross sections, very heavily pre

The goal was to observe which position of reinforcement yields the higher bearing capacity and to observe the failure modes in the models. To achieve the above goals, a short review of theoretical background concerning shear phenomena is performed. This, in order to enhance the

Abstract : Deep reinforced concrete beams are commonly used as transfer girders or bridge bents, at which its safety is often crucial for the stability of the whole structure. Such elements are exposed to the aggressive environment in northern climates causing steel-corrosion problems due to the excessive use of de-icing salts. Fiber-reinforced polymers (FRP) emerged as non-corroded reinforcing materials to overcome such problems in RC elements. The present study aims to address the applicability of concrete deep beams totally reinforced with FRP bars. Ten full-scale deep beams with dimensions

For architectural reasons, in some structural building systems, the need to change the direction of columns from one floor to another arises.

Abstract:

O dimensionamento de Regiões D (regiões em que não é aplicável a Hipótese de Bernoulli), embora amplamente estudado e discutido, é um tópico ainda em desenvolvimento e com normatização relativamente escassa. Os métodos mais comumente empregados são o Método dos Elementos Finitos (MEF) e o Método de Bielas e Tirantes (MBT). A dissertação expõe a base teórica e a metodologia dos dois métodos no dimensionamento de estruturas de concreto armado ao Estado Limite Último e aborda a utilização da otimização, em especial da otimização topológica, na definição dos modelos para o MBT.

Esta pesquisa discorre a respeito do comportamento estrutural de blocos de concreto armado sobre cinco estacas, dispostas nos vértices de um trapézio, e sobre seis estacas, com o arranjo retangular, considerado pilar com força centrada. Foram estudados diversos métodos analíticos para o dimensionamento dos blocos, no intuito de avaliar a compatibilidade entre o comportamento dos blocos e as hipóteses de cada método. Foi desenvolvida análise numérica tridimensional utilizando programa baseado no método dos elementos finitos. Nos blocos estudados variou-se a deformabilidade do solo de apoio das

Abstract:

Detta examensarbete vid Luleå tekniska universitet har utförts i samarbete med avdelningen för byggkonstruktionvid det nordiska konsultföretaget Norconsult AB. Arbetet bygger på en önskan från Norconsultatt ta fram en beräkningsmodell för höga balkar i överensstämmelse med Eurokod 2 motsvarande densom finns i BBK 04. Eurokod 2 har endast en knapphändig beskrivning av hur höga balkar bör dimensioneras.Detta skapar frustration och osäkerhet hos konstruktörer. Den tidigare svenska betongnormen,BBK 04, innehöll en tydlig och enkel mer empirisk beräkningsmetod för höga balkar, vilket gav en störres

Abstract:

A racionalização e a industrialização da construção civil têm promovido o sistema construtivo baseado em elementos de concretos pré-moldados. O comportamento das ligações entre os elementos pré-moldados constitui uma das principais preocupações dos projetistas, sendo as ligações entre a superestrutura e as fundações determinantes na estabilidade e na distribuição de esforços solicitantes da estrutura. O comportamento de blocos sobre estacas com ligações para pilares pré-moldados possui particularidades em razão do diferente mecanismo de transferência de forças do pilar para o bloco mediante a

Abstract:

En stor del av projekteringsskedet är framtagandet av bygghandlingar, främst ritningar i 2D. En modernare metod är istället att samla all information om ett byggnadsprojekt i en samordnad 3D-modell, så kallad BIM-modell. Building Information Modeling (BIM) är en välkänd projekteringsmetod som bygger på att digitala 3D-modeller innehåller tillräcklig information för att beställas och produceras i fysisk form. Modellen består av parametrar som representerar olika egenskaper och när en parameter ändras uppdateras modellen automatiskt. Parametrarna kan nås och modifieras av insticksprogram, så kal

Anhand von Versuchsergebnissen wird gezeigt, dass Stahlbetonbauteile mit textilbewehrtem Beton verstärkt werden können. Sowohl die Torsionstragfähigkeit als auch die Gebrauchstauglichkeit werden durch die textilbewehrte Verstärkungsschicht deutlich verbessert. Vergleichsrechnungen zeigen, dass die Torsionstragfähigkeit mit bereits bekannten Stabwerksmodellen ermittelt werden kann.

Abstract:

The finite element method is a powerful analysis tool which has facilitated a better understanding of the behaviour of reinforced concrete structures. Its use in the research field is widespread and complements experimental tests and the development of new analytical models. Its application in practice engineering has permitted to deal with complex elements. However, the general structural engineer is still reluctant to consider finite element modelling for his work as he finds most of these models excessively sophisticated for his needs and knowledge. In particular, complexity of many finite
