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

    Author : Sofia Utsi; []
    Keywords : 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

  4. 2. Sustainability-, Buildability- and Performance-driven Structural Design

    Author : Alexandre Mathern; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; sustainability; structural engineering; civil engineering; design method; finite element analysis; concrete structures; material developments; buildability; performance; structural developments; requirements; construction technology; integrated design; bridges; constructability;

    Abstract : The construction, maintenance and operation of infrastructure networks represent substantial impacts, both positive and negative, in all three dimensions of sustainability: economic, social and environmental. The greatest possibility to reduce the negative impacts and increase the positive ones is at the early design stage of construction projects. READ MORE

  5. 3. Psychological perspectives on performance-based compensation : Implications for work-related and health-related outcomes

    Author : Alexander Nordgren Selar; Magnus Sverke; Helena Falkenberg; Johnny Hellgren; Tomas Jungert; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; compensation; financial incentives; health; income; job performance; need satisfaction; pay dispersion; performance-based pay; self-determination theory; turnover intention; well-being; work motivation; psykologi; Psychology;

    Abstract : In the past decades, the contributions of individuals have come into greater focus on all levels of employment in many types of organizations. For example, this is manifested through an increased use of individual performance-based pay setting, where individual evaluations of employees’ contributions lead to diversified pay raises among peers.

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

    Author : Ragib Kadribegovic; Chalmers tekniska högskola; []
    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.

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

    Author : Torbjörn Stenbeck; Johan Silfwerbrand; Jan Bröchner; KTH; []
    Keywords : 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
