En studie av höghusbyggande med avseende på stomsystem och lastpåverkan

Vi har valt att undersöka vilka möjligheter och eventuella risker det finns att bygga högt i Stockholm. Undersökningen utgick på att jämföra olika byggtekniska lösningar för stomsystem. Hur tar stomsystemen hand om vertikala och horisontella laster? Vilket stomsystemen är lämpligast vid en viss höjd? Dessa är några av de frågor som besvaras i arbetet.De vertikala och horisontella lasterna är de faktorer som främst försvårar höghusbyggandet. Med en större belastning av laster ju högre det byggs måste stomsystemen dimensioneras med allt större noggrannhet för att lasterna ska nedföras till grundläggningen på ett säkert sätt.

Svensk-Rysk gradmätningsexpedition på Spetsbergen 1898-1914 : Ekonomiska överväganden och förändrade attityder med aspekt på åren 1898, 1902  och 1914

This study concerns the complete oeuvre by the British author Helen Zahavi: Dirty Weekend (1991), True Romance (1994), and Donna and the Fatman (1998). Her novels are here read as a trilogy dealing with the dialectics of gender and violence in 20th century discourse, drawing on theories of how the construction of subjects is produced by power, of the relation between power and sexuality.The heroines of Zahavi?s novels try their best to move about in a world where their freedom of movement is limited to their female identity. In Dirty Weekend the protagonist tries to shoot her way out, claiming revenge on every man that is forcing himself upon her. She gains some freedom of movement by refusing subordination, but does not really change the order of power.

Politisk Mobilisering och Kollektiva och Sociala Identitetskonstruktioner -en studie om dess interaktion med Nicaraguas Atlantregion som empiriskt exempel

This thesis is concerned with political mobilization and the construction of a collective andsocial identity. The main purpose of the study is theoretical which emphasize their interaction.In order to do this I study the two phenomenons by seeing them as cases of each other. Wecannot understand one of the two phenomenons without taking into account the other as well.In addition, the secondary aim of my thesis is empirical. I use the political transformationduring the 70th and 80th on the eastern seaboard of Nicaragua to relate my theoretical analysisof political mobilization and the construction of identities. Nicaragua will provide mytheoretical analysis with new insights.

Projektrisk : en studie av svenska bygg- och anläggningsföretag

Background: Today businesses are largely structured in projects and temporary organizations. In many companies, the ability to pursue projects is decisive for the business efficiency and competitiveness. The risk literature do not discuss identification and handling ofproject risk in building- and construction companies to a large extent, which has led us to investigate how project risk can be treated and handled in Swedish building- and construction companies. Purpose: The purpose of this thesis is to cover and describe business risk in Swedish building- and construction projects with focus on different risks and risk tools, and also to modify a model for evaluating the business risk maturity. Realization: This thesis has both traces of a case study and a cross-section study and examines eight different companies that are active in the building- and construction business.

Hur blir Peab ett mer attraktivt företag för kvinnliga ingenjörer?

The Swedish construction industry is dominated by men; however this is starting to change. The average age of Construction Engineers is high and approximately 40 per cent of the employees will retire by the year 2015. Currently, female engineers dominate the graduating classes of Swedish Universities but this is not reflected in the Swedish Construction industry.With so many female engineers available, why is this? Does it require a change in company culture and their condition of work to attract them? Is it the attitude towards women in the industry among the employees that has to be changed? Or is it a woman?s thoughts and prejudices of the industry that creates obstacles?The purpose of this final thesis is to describe how contracting firms in the construction industry can make themselves more attractive for female engineers. To reach the purpose, a study among salaried employees and craftsmen was conducted.

Säkerheten på en byggarbetsplats : Förhåller sig Skanska och dess underentreprenörer olika till arbetsmiljösäkerhet?

Approximately ten people die every year at building sites in Sweden. Every year TheWork Environment Authority (Arbetsmiljöverket) receives 3200 accident reportsfrom the construction sector. The Swedish building contractor Skanska has the vision:?Zero accidents?. Only at Skanska Sweden, where this diploma work is preformed,350-520 accidents and mishaps are reported every year for the last 5 years.

Enkätundersökningar i teori och praktik - med inriktning på folkbibliotek

The purpose of this thesis is to study to what extent the methodological theories are being reflected in the construction of user surveys at public libraries in Sweden. The study has been conducted as a qualitative literature study in two parts. The first part is an examination of literature concerning survey methodology; the second part is a study of three user surveys conducted at Swedish public libraries after 1995. Our main results indicate that the theories about methodology are followed in part, though it cannot be determined whether this is due to any actual methodological studies, common sense, or just copying other surveys. In our study we have found some areas of user survey construction that need further attention and that would benefit from more extensive methodology studies on the part of survey designers.

Konstruktiv utformning av vikplog

This project is about investigation and improvement of a V-plow for the company Swekip. A V- plow is used for snow removal but this product has been found to have deficiencies in its construction, breaking down and not living up to the desired objectives. This is because the product is ordered from a company in China where they have some problems with understanding the purpose of the plow.Initially the existing plow is investigated, all the shortcomings set out and examined, what is wrong and what needs improvement?When the solutions were done they were evaluated and examined that they actually live up to the desired requirements.This assignment is a pure construction project where the majority is implemented in CAD, where models are developed and FE analyses are carried out. But the project also includes a feasibility study, idea study and hydraulic design.The results are presented in the form of a CAD model and associated drawings that will serve as the manufacturing basis for the new V-plow.

Materiallogistik vid innerstadsprojekt : En fallstudie av ett innerstadsprojekt i förbättringssyfte av materialflödet

The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.

Miljömedvetenhet, miljöansvar och miljöbeteende En kvantitativ analys av det ekologiska medborgarskapets grunder

I samhällsdebatten om hur det hållbara samhället ska uppnås framhålls idag allt oftare individens bidrag till miljöproblemen samt dennes ansvar för sina handlingar och dess konsekvenser. Hur individbeteenden bäst förändras råder det dock delvis delade meningar om, och i den debatten står Ecological Citizenship-teorin för en syn på långvariga beteendeförändringar som styrda av vår inre motivation. Man antar ett samband mellan individens medvetenhet om miljökonsekvenserna av sina handlingar och dess beteende, och att detta samband förmedlas via en positiv attityd till individens personliga miljöansvar. Det är dessa samband som studeras i denna uppsats, med hjälp av statistisk analysmetod undersöks miljömedvetenhetens direkta och indirekta effekter dels på aggregerat miljöbeteende, och dels på tre olika typer av miljöbeteenden, nämligen resurssparande beteenden, transportbeteenden samt konsumentbeteenden.Resultaten av studien visar på att en indirekt effekt av miljömedvetenhet på aggregerat miljöbeteende via attityd till ansvar mycket riktigt föreligger, en dryg tredjedel av den totala effekten av miljömedvetenhet går vägen via ansvar. För de tre undergrupperna av miljöbeteenden framträder resurssparande beteenden som mest påverkade av både miljömedvetenhet och attityd till ansvar, men det är för transportbeteenden som den indirekta effekten utgör störst andel av den totala effekten.

Konstruktion av formkropp pa JAS 39 E/F Gripen

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

Varför Storbritannien? : Svenska uppslagsverk och det historiska förklaringsperspektivet (1907-1998)

Title: Why Great Britain? ? Swedish Encyclopaedias and the Explanatory Perspective of History, Essay in History AbstractIn my essay I describe how Swedish 20th century encyclopaedias interpret the coming about of the British Empire, the overall purpose being to establish a pattern of evolution in terms of historical understanding on the part of the encyclopaedic literature. Firstly, I have tried to determine whether the presentations at all constitute explanatory efforts. In those cases where they do, I have sought to ascertain whether the reasons put forward are to be understood as structural and stable, or as matters of less permanence. I have also tried to link these interpretations to significant ?constructions? of history ? i.

"Livsföring i övrigt" : En rättsvetenskaplig studie av kommunala riktlinjer för ekonomiskt bistånd

The purpose of this thesis was to examine the municipal guidelines regarding the construction of the prerequisite "other living expenses", and how the construction of the prerequisite was constructed in relation to the legislation. The sample of the thesis was the municipalities in Stockholm?s county. The empirical result was compiled with the hermeneutical method, and analyzed through a legal perspective and three different theoretical perspectives, as well as compared with previous studies. The theoretical perspectives were legal pluralism, bureaucracy, legitimacy and rule of law.
