  1. 1. Dynamic Blast Load Analysis using RFEM : Software evaluation

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Oskar Dädeby; [2021]
    Keywords : Blast load; Dynamic; RFEM; time history; experiment; time step;

    Abstract : The purpose of this Master thesis is to evaluate the RFEM software and determine if it could be used for dynamic analyses using blast loads from explosions. Determining the blast resistance for a structure is a growing market and would therefore be beneficial for Sweco Eskilstuna if RFEM could be used for this type of work. READ MORE

  3. 2. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    University essay from KTH/Betongbyggnad

    Author : Anton Frank; Andreas Fristedt; [2021]
    Keywords : Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Abstract : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.

  4. 3. Expansion of Sickla treatment plant : A study about the replacement of standard concrete to green concrete

    University essay from KTH/Betongbyggnad

    Author : Sava Tnar Rasool; Omar Sharif; [2020]
    Keywords : Cement classes; EPD; Exposure class; Fly ash; Green concrete; Ground granulated blast-furnace slag GGBS ; LCA; Portland cement; Silica fume; w c ratio; Cementklasser; Exponeringsklass; Flygaska; Grön betong; LCA; Mald granulerad masugnsslagg GGBS ; EPD; Portlandcement; Silikastoft; vct;

    Abstract : Stockholm Vatten has decided to close down the Bromma waste water treatment plantand manage the waste water from Bromma together with the waste water from the formerEolshällsverket to Henriksdal’s waste water treatment plant. Henriksdals wastewater treatment plant will be expanded for higher purification requirements and loads,estimated to be finished until 2040. READ MORE

  5. 4. Evaluation of a Programmable Hydraulic Valve for Drill Rig Applications

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jonathan de Brun Mangs; Mikael Tillquist; [2018]
    Keywords : Hydraulic valve; CAN; Drill rig; Rock drill; Blast hole drilling; Time delays; Ziegler-Nichols; PI-control;

    Abstract : The increase of intelligent systems can be seen in every industry. Integrated sensors and processors are used with internal control systems to create better performance for mobile hydraulic applications. The report describes how an evaluation was made to see if the productivity of a drill rig could be increased. READ MORE

  6. 5. 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
