  1. 1. Performance based concrete mix-design : aggregate and micro mortar optimization applied on self-compacting concrete containing fly ash

    Author : Sofia Utsi; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis is dealing with the field of self-compacting concrete (SCC). SCC is supposed to fill the form properly and enclose the reinforcement without any external vibration. The fresh properties of such a concrete are thus essential. SCC was first introduced in Japan in the middle of 1980th. READ MORE

  2. 2. Performance-based design of ventilation systems. Potential and limitations regarding indoor air quality

    Author : Ragib Kadribegovic; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; prescriptive design; indoor air quality; air cleaning; energy efficiency; performance-based design; recirculation;

    Abstract : It has been increasingly common to design for increased ventilation rates above legislative requirements specified in building codes and other norms as the most optimum way to improve indoor air quality. However, this concept has recently been challenged, for example, by studies demonstrating that the emissions or pollution from used traditional particle filters increases proportionally with air flow through the filter.

  3. 3. Promoting Innovation in Transportation Infrastructure Maintenance : Incentives Contracting and Performance Based Specifications

    Author : Torbjörn Stenbeck; Johan Silfwerbrand; Jan Bröchner; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Abstract : Knowledge of what action that is needed to drive innovation at a desired speed is in demand in civil engineering and its related maintenance. 1. What measures to stimulate innovation have been tested? 2. How much innovation has been achieved by contracting? 3. READ MORE

  4. 4. Fire safety design of road tunnels

    Author : Jonatan Gehandler; Avdelningen för Brandteknik; []
    Keywords : HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Abstract : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. READ MORE

  5. 5. Modeling pavement performance based on data from the Swedish LTPP database : predicting cracking and rutting

    Author : Markus Svensson; Sigurdur Erlingsson; Helge Mork; Statens väg- och transportforskningsinstitut; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cracking; Rutting wheel ; Prediction; Calculation; Mathematical model; Flexible pavement; Performance; Sprickbildning; Spårbildning; Förutsägelser; Beräkning; Matematiska modeller; Flexibla överbyggnader; Prestanda; 32 Road: Pavement design; 32 Road: Pavement design; performance predictions; LTPP; rut; crack; statistical modeling;

    Abstract : The roads in our society are in a state of constant degradation. The reasons for this are many, and therefore constructed to have a certain lifetime before being reconstructed. To minimize the cost of maintaining the important transport road network high quality prediction models are needed. READ MORE
