Because of its large ratio between strength and weight timber is a material very suitable for large span structures. For large spans of more than about 30 m, usually truss structures are adopted. The problem of large span timber truss structures are the expansive and complex nodes that have to be adopted, normally single or multiple slotted-in steel plates in combination with a number of dowel
Den här uppsatsen syftar till att undersöka hur skor fungerar som identitetsskapare hos individer. Uppsatsens titel är: Identitetsskapande genom skor – En studie om individers konsumtion i relation till deras identitetsskapande. Författarna till uppsatsen heter Sebastian Hallenius och Tomas Jermer och studerar Medie- och kommunikationsvetenskap på Institutionen för kommunikation och medier vid
Det finns få svenska studier som syftar till att undersöka större multinationella företags externa kriskommunikation genom sin medverkan i en debatt och syftet med denna studie är att belysa och problematisera detta. Syftet är att uppmärksamma eventuella strategier, sätt att argumentera och att studera på vilket sätt kommunikationen sker under en debatt. I denna uppsats är H&M studieobjektet o
Syftet med examensarbetet är att analysera några vanliga förstärkningssystem med kolfiber för en befintlig vägbro. Analysen görs ur ett ekonomiskt perspektiv där olika kolfiberalternativ jämförs. Syftet är också att jämföra tillvägagångssätt och resultat av klassning samt förstärkningsbehov för den befintliga bron, enligt gamla och nuvarande svenska normer. Examensarbetet är teoretiskt och bas
Today’s companies are using three dimensional finite element programs to evaluate structures of different kinds to a much greater extent than before, among them bridge structures. These programs can be divided into two groups: general and specialized programs. The general programs are general in the sense that they don’t focus on a specific type of structure and allow the user to model most st
Wind actions on roof-mounted solar collectors dier from those on an open range-deployment, due to turbulence and wind stream deection induced by the underlying building. As of December 2010, no construction codes in eect describes the wind loads on such structures, with the exception of the preliminary standard NVN 7250 from the Netherlands, with the latest draft released in 2007. The roofs consid
Physical protection is a necessity in all military operations regardless of purpose. It is thereby always a part of the operation and the demand will give an operational effect. The author's personal experience has led to a realization that a solution for temporatry physical protection is missing. Herein presents a solution for filling this gap. The solution is named Quick Response Cell System
The purpose of this Master’s Thesis is to investigate how the risk of onset of mould and decay will change due to a changing climate. The research encompasses the time period 1960-2099 in open fields near the cities Göteborg, Lund, Stockholm and Östersund for the emission scenarios A1B, A2 and B1. The risk of onset of mould and decay is studied on wood in outdoor climate as well as the risk of
Rapporten syftar till att jämföra två olika metoder som kan användas för att klassnings- beräkna broar. För att göra detta har en bro som tidigare klassningsberäknats deterministiskt av Reinertsen AB beräknats probabilistiskt. Skillnaden mellan metoderna har utvärderats genom att se vilka laster de olika metoderna tillåter, givet att bron klassningsberäknas i säkerhetsklass 2. Bron som används
This report contains a study of the structural loading capacity for driven concrete piles in cohesive soil. Two different types of models for handling horizontal loads have been investigated. The most common way in Sweden to cope with horizontal loads on piles is to drive the piles inclined in a truss pattern. The pile head is then thought to be hinged and the horizontal load is transmitted to th
Actors in the Swedish building industry have shown interest to build tall buildings in Sweden. It has historically been very few high rises and skyscrapers built and therefore the experience and traditions of high rise buildings are limited in Sweden. The aim of this thesis was to collect and present experiences from high-rise buildings, both from national and international high rise projects
Denna socialrättsliga uppsats utgör mitt examensarbete inom juristprogrammet. Syftet med studien är att klargöra om regleringen kring självbestämmanderätten inom hälso- och sjukvården tillåter särbehandling av äldre och om det i så fall orsakar avvägningsproblem i förhållande till självmordsbenägna äldre. För att kunna uppnå syftet har jag undersökt om hög ålder tillåts påverka element i självbestThis essay on social and welfare law is part of my final examination at law school. The aim is to clarify if the regulation about the right to self-determination in the Swedish health care system allows different treatment of elderly and if so is the case, if it causes problems in relations to conditions for suicidal elderly. The subject is relevant partly because elderly persons often are conside
The temperature on a bridge is a complex phenomena caused by several sources and it is quite difficult to forecast. Its effects cannot be ignored and during the last decades various studies have been made in this field. In order to reduce the complexity of these investigations, some simplifications, which do not entail large risks, are admitted making the problem easier to analyse. The main ob
An inevitable consequence of the increasingly larger buildings that we see around us is the demand for lighter construction components. Since floor slabs constitute the main part of the overall weight of multistory buildings, reducing their weight is a key step in reducing the overall weight of the construction. Usually this is done by using hollow core slabs or other types of all-concrete so
Design of a concrete column with biaxial moments and normal force is unpractical without the aid of a computer program. It is very time consuming to go through all calculations and to find a suitable layout of a cross-section and positioning of reinforcement for the final design. The goal of this thesis is to create a user friendly computer program for this problem. A critical pier in the Öland B
Determining the structural type of a bridge is often a difficult task. The purpose of this thesis is to preliminary design three bridge alternatives. The bridge shall cross the fjord Þorskafjörður in Iceland. The goal is to determine the most favorable option. That decision will be based on economy, construction and aesthetics. Following that a more detailed design of the superstructure is perfor
In this report a study is made of a sandwich wall especially produced for agricultural buildings. The wall contains two concrete slabs, one for the façade and one on the inside with insulation between them. The concrete slabs are joined together by lattice girders. The inner slab has a thicker cross section in it’s ends and less insulation, the girders also has a smaller distance between them. The
Today we are faced with the problem of a growing number of existing prestressed concrete bridge structures that are in need of repair work. With prestressed concrete in particular, it is difficult to anticipate how the stress distribution in an existing structure will be affected by the removal or addition of concrete due to repair work. With the impending implementation of Eurocode in Europe, th
Syftet med detta examensarbete är att ta fram och utvärdera en ny typ av brandskyddsisolering som gjuts direkt kring stålpelare och som ska användas vid industriellt byggande. Brandskyddet ska vara kostnadseffektivt, lätt att hantera samtidigt som det ska uppfylla de tekniska krav som ställs. De stålpelare som analyseras är sådana som är integrerade i innerväggar och i lägenhetsskiljande väggar.
Syftet med rapporten är att designa en avancerad byggnad som skiljer sig från en byggnad av standardmodell. Det är också av stort intresse att grundligt göra finita elementberäkningar på stomsystemet och visa hur kraftspelet blir i byggnaden i form av moment, tvärkrafter, normalkrafter och deformationer i bruksgränstillståndet.
