Modulenthus is a company in the wood house industry that builds houses in volumes. Volume building means that Modulenthus builds predecorated house volumes in a factory and transports these to the building sites where they are being put together to complete detached houses. The purpose of these Master Thesis is that, on the basis of Modulenthus conditions and wishes, evaluate a possible using of a

Fastighetsbeståndet byggt mellan 1940-70, med tegelfasader av skalmurstyp, har omfattande skador på grund av rostande armering och kramlor. Anledningen är att de stålsorter som användes för armering och infästning inte var korrosionsbeständiga fram till 1980-talet. Initialt uppträder problemen över öppningar där armering finns i det understa tegelskiftet. Då täckskiktet är otillräckligt börjar stå

There are many ways to construct a building. The designing team, structural engineers and architects, works together to find the best possible solution that will fulfill the owner’s whishes. In this process a structural system needs to be chosen. There are many factors that affect the selection of the structural system, but generally the most economical system is chosen. The factors that need to

Modulenthus bygger sina hus enligt volymprincipen, vilket innebär att de olika elementen till stommen byggs på olika linjer inne i en husfabrik. Dessa element sammanfogas sedan till större volymer. När volymerna står färdiga kan fönster och dörrar börja monteras och det invändiga arbetet såsom kakling av badrum och iordningställande av kök påbörjas. De inplastade volymerna transporteras sedan ut t

Sustainable Bridges is an EU-project. The objective of the project is to demonstrate that it is possible to enhance the load capacity of a bridge with refined analytical methods. This thesis will be a small part of the project. My objective in this thesis is to examine the dynamic loads generated in a bridge when trafficked. Since there are uncertainties concerning the dynamic effect this variable

This Masters Thesis’ purpose is to evaluate a number of methods used for dimensioning in order to avoid unwanted sway and vibrations in a light weight steel floor structure. The design methods studied in this report are done by Ohlsson, Hu, Onysko, Talja and ISO (no calculations or measurments are made for ISO). The study shows that there is no big difference in the longest span allowed by the stu

Analysis and design of a frame can be done in two principally different ways. The first method, calculation according to first order elastic theory, is based on buckling lengthsand interaction relations. The advantage with this method is its simplicity. The difficulty lies in the determination of buckling lengths. The second method, calculation according to second order elastic theory, results in

This report shows how an non-insulated sheet metal roof behaves when it is exposed to varying temperatures. What happens is that the sheet metal expands and contracts which can lead to damages in the sheet metal fasteners. This causes problems when the roof is ment to stabilize for horisontal forces on the building. This report focuses on a specific construction type that is the most commun in the

Composite steel and concrete structures can resist a fire, mostly because of the thermal properties of the concrete. This report examines a composite beam, HPC-beam, when the beam is exposed to standardized fire. The beam is designed after Eurocode and the Swedish national document. The material parameters are taken from the same sources. These material parameters are used as input data for applic

The Glass Ceiling is a proven and documented phenomenon for several countries. This paper tries to trace its existence of changing behaviour in the gender pay gap across the income distribution between the periods 1970 and 1990, and through a selection of professions for the highly educated individuals. This will show at the same time the transformation suffered by Swedish labor market between tho

Chronic Obstructive Pulmonary Disease (COPD) was ranked as the sixth leading cause of death in 1990 and is projected to be the fourth leading cause of death worldwide by 2030 due to an increase in smoking rates and demographic changes in many countries (Mathers & Loncar 2006). To diagnose COPD there are several methods which are either imprecise or very expensive. The objective of this master

In 1999 the Swedish government developed environmental objectives, as a driver to direct Sweden towards sustainable development. Swedish municipalities have a history of working strategically on environmental issues, through their local Agenda 21 management that was adopted by many municipalities in the mid-’90s. During the 21st century municipalities have, to a considerable extent, shifted from t

Printed media is a source of information widely available in society. In Denmark, hoarse political attitudes toward immigration created a climate of hostility which at the same time is reflected in the printed media, not only as a communication of what politicians say and do, but as a tone , perspective and angle when reporting. This culminated in 2005 with the publication of 12 cartoons criticizi

The present study is concerned with the expansion of biofuel production and two revealing and contrasting impacts caused in Honduras. The biofuels complex emerges as a sustainable alternative to cope with pressing problems related to climate change, energy insecurity and environmental degradation. However such an argument becomes problematic as land expansion for biofuels entails land-use changes

The mBlox Device Software, MDS, is a library that developers integrate into their applications to expose an API on the internet to access resources on a mobile device, such as an Android smart-phone. This report discusses the possibility to port the existing implementation of the mBlox Device Service from the Android Platform to the Blackberry Platform. In the time that was given a very much worki

Det skriftliga avtalet mellan två parter har länge verkat som garanti för upprätthållandet av den grundläggande avtalsrättsliga principen om att avtal ska hållas, både nationellt och internationellt. Men ska ett avtal alltid, under alla omständigheter, upprätthållas? Förändringar under avtalets bestånd kan göra avtalsvillkor betungande för en avtalspart. Skall en part likväl tvingas till avtalsu

Changes in the Swedish construction code introduced in 1994 enabled the construction of wooden multistorey buildings. This resulted in an increased need for knowledge about wooden structures in the building industry. The main issue in wooden framed buildings is disturbing vibrations and noise which propagate throughout the construction. It is valuable to be able to predict the behavior of future

One of the most common types of bridges in Sweden is the integral bridge. What characterizes the integral bridge is the lack of bearings and expansion joints. The advantage of this construction is that the horizontal forces can be distributed throughout the structure. A problem is the restraint forces that occur due to, for instance, changes in temperature. Integral bridges are now often designed
