  1. 1. Concrete flat slabs and footings Design method for punching and detailing for ductility

    University dissertation from Stockholm : KTH

    Author : Carl Erik Broms; Håkan Sundquist; Mikael Hallgren; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; bent-down bars; building codes; cyclic loading; deflection; ductility; earthquake; Byggnadsteknik; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Abstract : Simple but still realistic physical models suitable for structural design of flat concrete plates and column footings with respect to punching are presented.Punching of a flat plate is assumed to occur when the concrete compression strain at the column edge due to the bending moment in the slab reaches a critical value that is considerably lower than the generally accepted ultimate compression strain 0.

  2. 2. Penetrability due to filtration tendency of cement based grouts

    University dissertation from Stockholm : KTH

    Author : Daniel Eklund; Håkan Stille; Gunnar Gustafson; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; grout; grouting; penetrability; filtration tendency; Byggnadsteknik; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Abstract : Grouting as a method of strengthening and sealing rock, soil and concrete is widely used. The possibilities of sealing structures are of great importance from both an economical and environmental point of view. The cost of grouting has in certain projects been as high as the cost for the blasting and excavation of the tunnel. READ MORE

    Abstract : Previous investigations of Swedish and international dams have shown difficultiesto assess the safety against failure in rock foundations. The problem was alsogiven additional interest in connection to the recent construction of the newbridge at Traneberg in Stockholm. READ MORE

  4. 4. Airborne sound insulation of single and double plate constructions

    University dissertation from Stockholm : KTH

    Author : Ulrica Kernen; Gudni Jóhannesson; Waldemar Maysenhölder; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; : Airborne sound insulation; single plate; double plate; floating-floor; sound reduction index; sound transmission.; Byggnadsteknik; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Abstract : The sound insulation demands for dwellings and public building has increased over the years as the number of sound sources has grown. From the outside our homes are exposed to noise from cars, trains, airplanes, etc. Noise intrudes from our neighbours and their television and stereo equipments. READ MORE

  5. 5. Service life estimation in building design A development of the factor method

    University dissertation from Stockholm : KTH

    Author : Björn Marteinsson; Christer Sjöström; Michael A. Lacasse; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; factor method; service life prediction; durability; degradation; Byggnadsteknik; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Abstract : The built environment usually constitutes a very important part of the real capital of a nation, and the construction sector represents more than 10% of the yearly Gross National Product of the industrialised world. Good planning of all construction is important, and consideration of the service life of the work is of great interest and is a significant aspect of sustainability considerations. READ MORE
