Using an inclined screw brings many advantages compared to traditional methods, e.g. high load-bearing capacity, fast and easy montage and high fire resistance. This report contains a study of the influence end- and edge distances have on the load-carrying capacity in joints with inclined screws. Tests were carried out in order to determine if a few of the end- and edge distances proposed by Kevar

This report contains a theoretical study concerning composite construct design with steel and concrete and its mechanical and thermal interaction. The two primary advantages with this composition are the increase of the load-carrying capacity and its fire resistance. Composite construct elements are often used in the building process and there are several companies that offer a complete framework

Calculated deformations in glulam beams caused by moisture are based on linear moisture profile, this does not reflect reality. This report contains of a study where the moisture induced deformations are measured in three different test setups, simulating more realistic moisture exposure. After the beams are seasoned in RH 30 and 95 % the climate was changed, one group was in a moistening phase an

Today´s society depend on electric energy, in nuclear power plants this can be produced. Each nuclear reactor is situated inside a concrete containment reinforced with a post-tensioning system. The aim of this report is to analyse the state of the post-tensioning systems at Ringhals nuclear power plant. The purpose of a containment is to protect the outside world if an accident should occur. Tight

The purpose of this research was to determine how much the strength reduces in a slant nailed connection, which was examined for horizontal loads between stud and bottom plate in an infill wall. Slant nailing is commonly used in the workplace and is an alternative to metal plate connectors as they are both more expensive and more time consuming. However, there are no Swedish or European standards

This paper presents two methods of shear capacity design in two-dimensional membrane elements. The aim in this thesis is to find a method who calculates one resulting transeverse reinforcement instead of two. A procedure (Unified Shear Theory by Collins and Mitchells) is presented for design of transverse reinforcement in two-way concrete slabs. This procedure is compared to the Swedish procedure

Today, the knowledge about ice forces in Sweden is uncertain. Certain guidelines have been developed according to RIDAS to determine ice forces when constructing dams, piers etc. In this thesis an environmental model has been developed to predict thermal ice pressures. The inputs for the model are; a) the mean daily air temperature for each day of the year; b) the snow cover depth. The mean daily

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

The aim in this thesis is to itemize materials with ADT. The material’s lists shall then be transferred from ADT to Access and furthermore to Jeeves. The aim also is to describe the PDM-system and to find out if this PDM-system can cooperate between ADT and Jeeves. I also tried to study the possibility of transferring the material’s lists from ADT to the PDMsystem. I found that the material’s list

Vid nybyggnation av betongkonstruktioner ställs höga krav på livslängd och kvalitet. En starkt bidragande faktor till ökad livslängd för etongkonstruktioner är täckskiktets tjocklek. Ett stort täckskikt skyddar armeringen då det hindrar att karbonatiseringen når in till armeringen. Användandet av större täckskikt resulterar dock i svårigheter att klara dagens krav på maximalt tillåtna sprickvidder

Danogips has introduced tongued and grooved gypsum boards which can be used regardless of the distance between the studs in the framework. The goal of this thesis is to evaluate the material properties of the new gypsum product and compare it to conventional gypsum walls. Literature studies and three different experiments are carried out. The stiffness of the construction is measured by applying 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

Peab har utvecklat vägbyggnadskonceptet SwePave för att optimera olika överbyggnadskonstruktioner med bland annat stabiliserat packat material. Denna metod går även att använda för att stabilisera jorden förgrundläggning av nya byggnader. Där stabiliserat material använts för att förstärka jorden behövs även en metod för att förstärka för de punktlaster som nedförs av stomkonstruktioner. För att f

A progressive collapse implies a structural failure initiated by a local damage which subsequently develops, as a chain reaction, into a failure of either the entire structural system, or only a part of it. The collapse of the Ronan Point building in London 1968 prompted numerous efforts to develop structural design criteria to prevent progressive collapse. Improved design procedures with the inte

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

In the 1940-ies curtain walls were introduced, i.e. brick walls that do not have any bearing function but served as a front material. Horizontal reinforcement was used in this kind of walls, partly over and under openings or, in undisturbed wall fields, every 5-6th bed joint. In this work the tensile bond strength of mortar joints repaired with an injection tool and a manual method respectively is

The aim of this study is to examine how a new area of work is emerging, and how the organization´s framework and guidelines affect the professionals´work. In 2010 a law, concerning the child´s right to be involved when a parent suffer from serious illness, was extended to give these children an enhanced protection. We also want to highlight how the professional´s works are affected of the organiza

Not long ago large cash holding in balance sheet would not be recommended. As we know, large cash in hand means the companies less invest in new projects and extend their business. However, the recent research reveals that U.S companies hold more cash than before, and the financial strength might have strong relationship with the performance. Especially during the financial crises, those who reser

Syftet med studien är att undersöka ifall något samband mellan fondprestationen och de organisatoriska fondegenskaperna existerar. Studien ska bidra till en ökad förståelse för hur olika fondegenskaper i fonder kan komma att påverka en fonds prestation. Mer exakt så syftar studien till att kunna förklara relationen mellan en fonds prestation och antalet fonder i fondfamiljen, antalet personer invo

Abstract Value at Risk (VaR) is a simple, transparent and consistent measure that summarizes all sources of downside risk. VaR has gained acceptance in the banking industry in accordance to Basel II rules which require banks to use VaR in calculations of market risk. VaR as a risk measure is not as widely accepted in the investment industry. This thesis embraces five different VaR models to 20 equ
