I Sverige finns det ett stort antal ekonomibyggnader som är byggda med traditionell timmermansteknik. Merparten är upprättade mellan 1870 – 1940, ofta byggda i egen regi utan att laster beaktats eller dimensioneringsberäkningar utförts. I dagsläget finns det standarder som beskriver hur en lämplig dimensionering av moderna konstruktioner och förband bör utföras, men inga riktlinjer för hur äldre träförband kan kontrolleras.   Målet med examensarbetet är att med utgångpunkt från Eurokoder göra en approximativ hållfasthetsberäkning av de förband som återfinns i takstolen i ett studerat objekt, med syfte att avgöra huruvida Eurokoder är lämpliga som beräkningsmedel för äldre träförband.   Resultatet visar att vissa förband i hög grad är beroende av att krafter kan tas upp via friktion, vilket är något som inte beaktas i Eurokoder. Dessutom innebär de säkerhetsfaktorer som Eurokoder medför att en del förband anses underdimensionerade. / There is a large amount of outbuildings built with traditional cogging technique in Sweden. Most of them were built in 1870-1940, often without proper dimensioning. Today there are standards describing how to properly dimension modern structures and joints, but there are no standards describing how to verify the strength of older wooden joints.   The objective of the thesis is to approximate the strength of the joints found in the truss of an actual outbuilding by using Eurocodes, with the purpose to determine whether the Eurocodes are suitable as a calculation tool for older wooden joints.   The result shows that curtain joints are highly dependent on forces of friction to counteract the strain of the joints, which is something that is not taken in to account in any of the Eurocodes. Additionally some joints are considered underdimensioned do to the safety factors the Eurocodes entails.

This thesis discusses how to test the mechanical properties of openlattice truss structures and hybrids being a tube containing a latticetruss structure. By properties we mean strength, stiffness, thermalconductivity and so forth.Mechanical testing was done on two different structures to betterunderstand how the load-bearing properties change when these structuresare subjected to tensile, compressive and bending forces. The structuresinvestigated were Diamond and Octagon built at 45° and 90°. Acousticemission was also used to evaluate and analyze the different behaviour ofthe structures. The test results were used to produce design criteria forproperties in different cell structures manufactured of Hastelloy X™. Amap with design criteria containing stiffness and weight per cubiccentimetre was produced for parts that would be subjected to compressiveforces.

The aim of the master's thesis is to design an environmentally advanced gym building. In the first part, the building structure is designed. It is a two-storey building. On the first floor there is a reception, a gym, sanitary facilities for athletes, communication areas, facilities for employees, storage areas and technical facilities. On the second floor there is a cafeteria, gym, sanitary facilities for athletes, tribune, communication areas, toilets, staff facilities and technical facilities. The structural system is a skeleton of monolithic reinforced concrete with infill masonry of aerated concrete. Ceiling structures and staircase are also designed as monolithic reinforced concrete. The building is roofed with trussed steel gable trus-ses, the roof cladding consists of PUR boards with surface trapezoidal sheeting. The perimeter walls are insulated with ETICS system. The second part deals with the building environment technology. Heating, air conditioning, cooling, water management, lighting and a photovoltaic power plant are designed. The third part is an energy study for the design of the heating source. Economic and ecological factors are taken into account. The decisive parameters for the selection of the most optimal solution are the total investment costs over the lifetime, the production of CO2 emissions and the consumption of primary nonrenewable energy. The project is developed using AutoCAD and DEKsoft software.

Geodetic measurements with a gyro theodolite are an important technique for establishing control networks in tunnelling projects. The observations are used as a separate control point outside the main network while checking the angle of the tunnels direction as it is difficult to connect the underground network to a superior network outside the tunnel.  This study aims to investigate the usefulness of gyro surveys in tunnel networks and evaluate how much they improve the positional accuracy of underground control networks. The study compares a total of four network simulations (with and without gyro observations) that have been divided into 12 sections. The sections are then compared to each other to determine the influence of gyro observations on the positional uncertainty in the network. Gyro observations were found to contribute to significant improvements in measurement data. Without them the tunnel would have an uncertainty greater than five centimetres within approximately 1000 m. The results provide valuable insights into the impact of gyro measurements on geodetic control network in tunnels and how they can be used to improve measurement data. / Gyromätningar och gyroteodoliter har idag en viktig roll på grund av de höga krav på noggrannhet som ställs inom många av dagens tunnelprojekt vid stomnätsmätning i tunnlar. Gyroobservationerna används för att få en utomstående kontroll av stomnätet då detta på grund av tunnelns utformning är problematiskt att koppla mot ett överordnat nät. Det finns dock inte mycket skrivet om hur dessa bör användas samt hur stor effekt mätningarna har på ett vanligt tunnelbygge idag. Studiens syfte är att undersöka gyromätningar användbarhet i tunnelnät samt utvärdera hur mycket dessa förbättrar noggrannheten på kortare stomnät i tunnelmiljö. I rapporten har sammanlagt fyra nätsimuleringar för en tunnelbana i Stockholm jämförts med varandra där två tillhör byggnätet och två bruksnätet (med och utan gyroobservationer). Dessa har delats upp i totalt 12 sektioner varav 6 stycken innehåller gyroobservationer och 6 är utan gyroobservationer. Sektionerna har sedan jämförts med varandra för att ta reda på hur stor inverkan gyroobservationerna har på osäkerheten i näten samt om det är möjligt att nå upp till en teoretisk osäkerhet i nätet på max fem centimeter. Resultatet visar att den radiella medelosäkerheten minskade från 1,69 cm till 0,93 cm i sektion 1, 1,24 cm till 0,64 cm i sektion 2 och 7,13 cm till 1,64 cm i sektion 3. Vid genomslaget mellan sektion 1 och 2 minskade osäkerheten från 5,10 cm till 1,14 cm i sektion 1 och i sektion 2 från 4,41 cm till 1,48 cm. Sträckan på fackverksnätet innan osäkerheten översteg fem centimeter blev 794m i sektion 1 och 846 m i sektion 3. I sektion 2 översteg aldrig osäkerheten fem centimeter trots att längden på fackverket var 971 m. Sektion 1 och 2 i bruksnätet visade ingen betydande förändring beroende på om gyroobservationer användes eller inte. I sektion 3 minskade dock den radiella medelosäkerheten med 2,29 cm vilket kan förklara genom att stomnätet inte har något anslutningsnät i slutet på denna sektion. Generellt visades gyroobservationerna bidra till stora förbättringar av mätdata i byggnätet och utan dessa skulle tunneln inom ca. 1000 m ha en osäkerhet större än fem centimeter. Resultatet ger en bra inblick i hur stor påverkan gyromätningar har på stomnät i tunnlar samt hur dessa kan användas för att förbättra mätvärden.
