  1. 21. Response of Buildings Exposed to Blast Load - Method Evaluation

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Carl Löfquist; [2016]
    Keywords : Explosion; Blast Wave; Impulse; Rayleigh-Ritz metod; Ritz vectors; Computational effeciency; Modal Reduction; Eurocode; Technology and Engineering;

    Abstract : Due to accidental external explosions ,which is not handle in the Eurocodes, are structural designers looking for other ways to design loads for external loads due to explosions. This combined with lighter building structures is a reason to address the issues of analysing the dynamic behavior of buildings subjected to air blasts from these extreme situations. READ MORE

  3. 22. Evaluation of 3D dynamic effects induced by high-speed trains on double-track slab bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Jossian Thomas; Assís Arañó Barenys; [2016]
    Keywords : Dynamics; Frequency analysis; 3D model; Torsional modes of vibration;

    Abstract : In addition to a static design, a dynamic analysis has to be performed for bridges for which the maximum permissible train speed exceeds 200 km/h. This analysis requires a lot of computing time, for this reason Svedholm and Andersson (2016) have developed a simple tool describing the relationship between the first eigenfrequency of the bridge, the span length and the minimum mass to fulfill the regulation specified in EN-1990.

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : YUCHAO LI; [2016]
    Keywords : ;

    Abstract : Skogsindustrin är en stor del av Sveriges ekonomi. Med hjälp av den så kallade kapa till längd metoden, vilket betyder att träden först kapas till lämplig längd och sen forslas de till sidan av en väg med hjälp av "forwarders", går det det uppnå hög produktivitet och automatisering.
