Jämförelse mellan BKR/BSK och Eurokoders behandling av utmattning i traversbalkar med tillhörande svetsfogar

This report has been performed for WSP Construction Design located at Arenavägen 7 in Stockholm. WSP Construction Design is one of the leading departments in Sweden in construction solutions regarding everything from building construction to industrial building. Great competencies regarding steel, wood and concrete constructions are available within the department which is well sought.Crane girders used in the industry are exposed to large loads that vary over time that includes instantaneous lifts and the crane girders movement which lead to the phenomenon fatigue in the crane girder and its ingoing welds. A control of fatigue needs to be performed after a certain lifespan measured in time which in turn is converted to a number of loadcycles. When the number of loadcycles amounts to a greater number the input welds resistance will have been reduced and the rate of utilization thereby increased.

Dimensionering av grundläggning med hjälp av Eurokod

AbstractWork to develop the Eurocodes started in 1975 by the European Commission adopted a program to eliminate trade barriers within the construction area. The goal was to create common European design standards that would replace the member countries' own rules. Eurocodes will replace The National Board of Housing Building and Planning, National Rail, The National Road Administration and other agencies' calculation rules for the buildings structures. The transition to the use of Eurocodes looks like this:Eurocodes set to Swedish standards  between 2002 ? 2007They can be used parallel with national standards 2006 - 2009 The total transition is at the end of 2010/2011.Right now is going on a lot of work for replacement of the existing standards to Eurocodes.  The transition to the new calculations` standards, many construction companies and consulting firms facing a big changes and competitions.

Momentbärförmåga för semikompakta ståltvärsnitt av HSQ-balkar : En modell för interpolering mellan eurokodens klass 2 och 3

The current standards for design of steel beams are divided into four classes based on the slenderness of cross-sectional parts. Depending on the section class a beams load capacity is either determined by a plastic, elastic or a reduced elastic model. The division between cross-sections calculated by a plastic and an elastic model is today done in a very harsh way with no smooth transition. This leads to a large difference in the calculated resistance for the sections located near the class limits. Elasto-plastic sections are in the current situation calculated as purely elastic and their large plastic reserve is not considered in the current standards.

Eurocodes : Beräkningsjämförelser mellan eurocodes och BKR

In the year 2010 a transition will take place here in Sweden from the present rules how to dimension buildings in to the common rules with have been developed in Europe, the Eurocodes. Eurocode is the term for a collection standard that contains calculation rules in how to dimension constructions and buildings. They are developed by the European standardize committee.The purpose with this examination work is to get an insight of what changes this will contribute to, and how it will affect the dimensioning. Are there going to be any differences in the dimension you finally chose?To investigate these possible differences two constructions will be calculated first in the present Swedish rules, and then in the coming eurocodes.One of these two constructions will be build completely in steel, while the other will be build completely in concrete.

Dimensionering av betongkonstruktioner : En jämförande studie av BBK 04 och Eurokod 2 vid dimensionering av balkar och pelare

Today, we use BKR and BBK 04 when designing concrete structures inSweden, which will, in the near future, be replaced by Eurocode 2. When you are designing buildings, you will use Eurocode 2 Part 1-1 and with this new standard, some new rules and general rules will be necessary to adopt. To examine how BKR and BBK 04 tells apart from Eurocode 2 when designing concrete structures, one beam and one column with often common dimensions, is studied. The beam is designed with consideration of (considerate to) durability at bending moments, shear forces and control of cracking. The column is designed with consideration of durability at eccentric axial load and bending moments in cross section on account of (due to) geometric imperfections. BBK 04 has gone one step closer to Eurocode 2 than earlier editions and the things that are different, when calculating reinforcement, is how they use the partial factors.

Samverkanspelare i icke bärande fasadelement

AbstractThe tests work is about the subject "synergism of steel and concrete."The construction sector is in a strong competition and the different companies in the PrefabMarket has ever tried to develop new design solutions that are efficient and environmentallyfriendly.The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .

KONTROLLBERÄKNING AV ETT TAKRAS PÅ EN TENNISHALL I NYKÖPING : En jämförelse mellan Eurokod och BKR

?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.

Plattgrundläggning enligt Implementeringskommissionen för Europastandarder inom Geoteknik

Den förste januari 2011 blev det obligatoriskt att i Sverige följa dimensioneringsförskrifterna Eurocode 7 vid dimensionering av geokonstruktioner. Eurocode är ett resultatet av det Europeiska standardiseringsorganet CEN?s arbete med att ta fram gemensamma regler för hela Europa.Eurocode ersatte BKR som tidigare var de normativa föreskrifterna som gällde i Sverige och med detta skifte startades arbetet med att implementera de nya reglerna fullt ut bland de svenska konstruktörerna.På uppdrag av ett lokalt företag har det jämförts och lokaliserat ändringar som gjorts mellan de nya reglerna i bilaga D och de regler som ska appliceras i Sverige. Det har även konstruerats ett beräkningsprogram som dimensionerar grundfundament enligt de nya reglerna som föreskrivs i Eurocode 7, utifrån IEG?s hänvisningar.Resultatet från undersökningen visar att de nya dimensioneringsföreskrifterna från EU inte innebar en så stor skillnad från BKR?s regler som först troddes utan den gav stor frihet till att räkna med de metoder som respektive land själva väljer.

Inverkan av försvagningar på bärförmåga för stålbalkar med långa spännvidder : En jämförelse mellan Eurokod och BKR

The purpose of this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both an architectural perspective as well as from a building services perspective by creating an opportunity for building installations.The objective of this thesis is to examine how much an I-beam can be weakened without sacrificing safety and functionality. The investigation has been done by using Finite Element Method through commercial software.The regulation for structural design of building structures in Sweden used to be specified in the document known as BKR. But this was replaced by the European norm Eurocode back in May 2011.

Transition till demokrati: strukturella faktorers påverkan i de begränsade flerpartisystemen Kenya och Tanzania

This paper deals with institutional and structural factors' influence on democratic transition in limited multiparty regimes in Sub-Saharan Africa. Comparing the cases Kenya and Tanzania, of which the former has made a transition to democracy and the latter has not, this paper reaches the conclusion that political traditions, the coalescing of the opposition, and the elites ability to learn from the electoral process is essential for a transition to democracy. In the specific cases, the harshness of the Moi regime and the Tanzanian vision of national unity may possibly carry some explanatory power, alongside the pressure from international actors.These results have been reached through the application of a comparative case study, where democratic transition constitutes the dependent variable. It should be noted that a harsh definition of the term transition has been applied, according to which the incumbents actual loss of an election is a necessary indicator for transition. However, the Freedom House and Polity scores have been brought up as complement of this definition.

Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

Vidhäftning mellan prefabelement och pågjutningsbetong : Undersökning hur skrovligheten påverkar vidhäftningskapaciteten vid skjuvning

Self-compacting concrete has soon been around for a decade. Recently the prefabrication industry has started to use this fairly new concrete type in larger scales, mainly because of its distinctive properties.  There are still certain areas that need to be thoroughly examined, such as bond capacity. There have been very few studies regarding shear capacity due to the fact that the procedure is complicated.This report will highlight a method to examine the shear capacity of different surfaces that have been prewetted as well as non-prewetted surfaces. The surface areas follow BBK 04?s and Eurocode 2?s demand for surface roughness.  A smooth surface will be completed in order to confirm if the different shapes influence the bond strength by shear stress or not.                       The purpose of this essay is to measure the bond strength within the shear capacity as well as examine the impact it has on surface roughness and treatment for shear bond.The method used to identify the shear capacity is called L-shaped Push-Off Test.

Transition hos närstående som vårdar en familjemedlem drabbad av stroke

Människor som drabbas av stroke får ofta allvarliga komplikationer. Sjukdomen medför en förändrad framtid även för den närstående som tar på sig en vårdande roll. Syftet med denna litteraturstudie var att beskriva upplevelsen av transition hos närstående som vårdar en familjemedlem drabbad av stroke. Analysen resulterade i sex kategorier: söka kunskap och insikt: svårigheter att anta nya roller: leva i en förändrad relation: erövra en ny normalitet i livet: hitta tillbaka till sig själv och omvärdera prioriteringar i livet. Resultatet beskriver att transition är en komplex process som integrerar många delar av människans livsvärld.

Tillämpning av 6 b § LAS vid sammanslagningar av företagshälsovårder : Anställningsavtalets skillnader vid pensionsbestämmelser

During year 2007 ClaraHälsan Ltd bought the company health service Solstahälsan in Karlstad. The wide merger of the two health services the problems arose around the employees? employment agreements when certain parts of the agreement differ. At a transition of a company, in this case a health service, the rights and obligations for the employees will pass on to the new employer according to directive 2001/23/EG who came in force in the swedish legal system in year 1995. The former employer is only responsible vis-à-vis the employees ?for economic obligations related to the time before the transition, the code of protection of employment 6 b §.
