1. 1. Laboratory testing of shotcrete with fibres of steel, basalt or synthetic materials

   Master-uppsats, KTH/Betongbyggnad

   Författare :Muralidharan Rengarajan; [2020]
   Nyckelord :Fibre reinforced shotcrete; Energy absorption; Residual strength; Fibres; and Laboratory testing;

   Sammanfattning : Shotcrete or sprayed concrete has become an inevitable material for stabilising and supporting hard rock tunnels. To prevent rock block fallouts in the excavated tunnel, shotcrete is pneumatically projected under high pressure on the rock surface. LÄS MER

3. 2. Seismic evaluation and retrofitting of an existing building in Athens using pushover analysis

   Master-uppsats, KTH/Betongbyggnad

   Författare :Angelos Lazaris; [2019]
   Nyckelord :Earthquakes; seismic analysis; retrofitting; pushover analysis; concrete building; steel bracing; fibre reinforced plastic;

   Sammanfattning : Earthquakes are one of the biggest problems in civil engineering all over the world. Due to earthquakes, great disasters in cities with collapsed structures and human losses have been caused. LÄS MER

4. 3. Dimensionering och analys av stålfiberarmerad betong : En mekanisk, ergonomisk och ekonomisk jämförlelse med konventionell armerad betong

   Uppsats för yrkesexamina på grundnivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

   Författare :Nezar Pirgholizadeh; Tafid Krikor; Jeny Krikor; [2019]
   Nyckelord :stålfiberarmerad betong; konventionell armerad betong; dimensionering enligt svensk standard; jämförelse mellan stålfiber och konventionell armering; sprickbildning; tvärkraftsdimensionering; momentdimensionering;

   Sammanfattning : The purpose of this study was to investigate the properties of steel fibre reinforced concrete and its design models in relation to conventional reinforced concrete from a mechanical, economical and ergonomic perspective. Design examples were also presented for beams and slabs-on-ground for their shear and moment capacity. LÄS MER

5. 4. Design of Ultra High Performance Fibre Reinforced Concrete Bridges : A Comparative Study to Conventional Concrete Bridges

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Viktor Eriksson; [2019]
   Nyckelord :Bridge design; CO2 emissions; Mechanical properties and behaviour; Straight short steel fibres; UHPC; UHPFRC; Bro dimensionering; CO2 utsläpp; Korta raka stålfibrer; Mekaniska egenskaper och beteende; UHPC; UHPFRC;

   Sammanfattning : The use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in the construction industry started in the 1990s and has since then been used for bridges all over the world. The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed.

7. 5. Tillämpning av kolfiberförstärkning i bärande betongkonstruktioner : Jämförelse med stål som förstärkningsmaterial

   M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Författare :Johan Högström; David Johansson; [2016]
   Nyckelord :CFRP; FRP; CFRP materials; reinforced concrete; composites; fiber composites; carbon fiber; NSMR; strengthening concrete; Kolfiberförstärkning; fiberförstärkningar.;

   Sammanfattning : Strengthening of existing structures with Carbon Fibre Reinforced Polymers (CFRP) is a method that has been more common in the building sector during the last decades. The materials strength in relation to its weight is a huge advantage but the lack of knowledge in the building sector results that professionals uses more proven materials such as steel to strength structures.
