  1. 6. Natural corrosion in reinforced concrete structures

    Författare :Samanta Robuschi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural corrosion; pitting corrosion; reinforced concrete structures; chloride-induced corrosion.; neutron imaging; anchorage; plain bars; X-rays CT;

    Sammanfattning : Among the threats to the durability of concrete structures, corrosion of the reinforcement bars is undoubtedly the most common one. Corrosion damages impair safety and durability of infrastructure, and assessment of the safety is challenging due to the complex nature of the corrosion process. LÄS MER

  3. 7. Simulation of Combustion and Fire-Induced Flows in Enclosures

    Författare :Heimo Tuovinen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cumbustion; Chemical kinetics; Flamelet model; CFD models; Fire-induced flows;

    Sammanfattning : Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. LÄS MER

  4. 8. A ground-borne noise prediction model for railway traffic in tunnels in bedrock

    Författare :Fatemeh Dashti; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway tunnel induced vibration; Ground-borne noise and vibration; Wave propagation in bedrock; Prediction of noise.;

    Sammanfattning : Human life has become more manageable by the expansion of railway lines. However, despite providing convenience, railways increase noise and vibration in residential areas. Vibrations and noise generated by railways may harm human health, cause cosmetic damage and have an adverse impact on the environment. LÄS MER

  7. 10. Managing yards and togetherness: living conditions and social robustness through tenant involvement in open space management

    Författare :Pål Castell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; housing management; urban neighbourhoods; participation; resident involvement; territoriality; social exclusion; social cohesion; collective action; open space management; social capital;

    Sammanfattning : The subject of this thesis is tenant involvement in open space management in the context of Swedish rental housing areas. When tenants become involved in the management of the shared open spaces in their housing area, it affects their relationships to the place, to each other, to the landlord and to the city in different ways.
