Modulenthus bygger småhus enligt principen volymhus, det vill säga att så mycket som möjligt färdigställs på fabrik så att huset kan levereras direkt till byggplatsen som ett antal volymer med golv, väggar och tak. Husen ställs på en krypgrund, en typ av grund som alltid blivit kraftigt ifrågasatt och på senare år uppmärksammad i media på grund av den stora andelen fuktskadade grunder. För att lig

In the period between 1940s and 1970s the widespread practice in Sweden was to use non-stainless steel reinforcement in masonry walls. In many cases cracks started to appear in joints above openings in these walls because of corrosion of the reinforcement. The largest problem is that the appearance of damaged buildings deteriorates and there is a risk of bricks falling down and rain water penetrat

This Master’s Thesis investigates whether expansion joints should be placed between fields of ceramic tiles, which are recommended by distributors today. This thesis concludes that expansion joints do not relieve in-plane stresses in ceramic tile coverings attached with the thin-set method. As shear stresses in the adhesive layer in the vicinity of expansion joints can reach critical levels, using

The wind effects on high rise buildings were studied by finding and reading books, articles and studying equations. This was done to calculate the first natural frequency of high rise buildings, wind induced acceleration on high rise buildings and how the comfort criteria of acceleration performing on high rise buildings acts on human bodies living in the building. The buildings that were studied

Syftet med rapporten är att kartlägga och analysera hur värdeflödet i samband med platsgjutning av en stomme fungerar idag, med avseende på bland annat arbetsfördelning, genomloppstider, resursanvändning, mellanlagring och informationsflöde. En utvärdering görs av hur metoderna Activity sampling och Värdeflödesanalys fungerar för kartläggning inom byggbranschen och hur resultaten från studier med

Tall buildings have lately become a problem to design because of the development of light weighted steel frames and wind loads. An important task of a structure is the absorption of horizontal loads and the capacity to transfer the resulting moment down into the ground. It is the engineer’s task to make sure that the structure’s performance is sufficient when it comes to safety and serviceability.

Dagens byggande av bostäder präglas av ökade krav på kortare byggtider, lägre byggkostnader och en jämn och hög kvalitet. Miljötänkande har också fått en allt högre prioritet. De ökade kraven har medfört olika typer av satsningar på att förbättra material, teknik och metoder för att bygga villor. En tydlig linje i denna utveckling har varit en ökad användning av förtillverkade komponenter och elem

The industry of engineered nanoparticles (ENPs) has grown rapidly during the last decade, with for example carbon nanotubes (CNTs) incorporated in high-tech composites and nanosized TiO2 in sunscreens and paint. With an increased potential of human exposure to these novel ENPs, especially during production and handling of nanoparticles, the concern of risks when people become exposed has increased

The thesis examines two emergent religiosities which flourish among university students and young professionals connected with the private media field in Beijing. One case group consists of young successful professionals from the field of private media who have started to worship a living Buddha of the Vajrayana school. The other group consists of students from universities connected to the privat

Uppsatsen undersöker vilken bild av arbetsmarknaden som förmedlas till arbetstagare av så kallade coacher och undersöker hur bland annat psykologisering och individualisering spelar in i sammanhanget. Frågeställningen är vilken ideologi och vilka maktrelationer som förmedlas och reproduceras samt vilken diskurs de ingår i. Det empiriska materialet utgörs av två coachningsböcker riktade till arbets

The deployment of BIM (Building Information Modeling) in the Swedish building industry has begun. A BIM-model, briefly explained, is an object orientated 3D model that contains the available information about a building. Currently it’s mostly used for enabling a more effective collision control, quantity takeoff and production of shop and construction drawings. Thanks to its 3D nature it is easier

In Sweden there has recently been a change in the code from the former BFS2010:2 BKR 13 to Eurocode 5. This shift has led to changes when calculating the design capacity for all materials including wood. One of the parameters that were changed was the strength of wood perpendicular to the grain. The characteristic value required was decreased from 8 MPa to 2.7 MPa which have a relativity large imp

The purpose of this Master Thesis is to observe how well the standard EN 12354, the computer program Bastian, and field measurements agree with each other. Calculations on two different objects, where one object cointained four different constructions, were compared with data from field measurments. The restrictions of EN 12354-1&2 and Bastian were evaluated from this. The areas of application

This research is based on the investigation of a Biosphere Reserve in the South of Mexico. It observes the Vision and Mission of the Biosphere Reserve Sian Ka’an in Quintana Roo Mexico based on the norms given by UNESCO’s Man And the Biosphere. It also tries to examine the Reserve’s opportunity for sustainability science to be a knowledge co-production and exchange platform. And its prospects to b

This study has been done on the Chittagong Hill Tracts (CHT) ‘Peace Accord’ in Bangladesh which is the policy response of government to address socioeconomic, educational and cultural rights of the indigenous people. In this context, my study illuminates on two concepts namely ‘participation’ and ‘peacebuilding’. Here, the main research question is : How far does ‘Participation’ function as an eff
