  2. 11. Life-Cycle Costing : Applications and Implementations in Bridge Investment and Management

    Author : Mohammed Safi; Raid Karoumi; Håkan Sundquist; Jan-Eric Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge; Cost; Life Cycle Cost Analysis; Procurement; Investment; Management;

    Abstract : A well-maintained bridge infrastructure is a fundamental necessity for a modern society that provides great value, but ensuring that it meets all the requirements sustainably and cost-effectively is challenging. Bridge investment and management decisions generally involve selection from multiple alternatives. READ MORE

  5. 13. Durability of timber members : Moisture conditions and service life assessment of bridge detailing

    Author : Jonas Niklewski; Avdelningen för Konstruktionsteknik; []
    Keywords : wood; spruce; moisture; durability; decay; service life; detailing; model;

    Abstract : The longevity of timber structures in exposed outdoor environments is often perceived to be unreliable as compared with that of concrete and steel structures. This situation is exacerbated to some extent by the fact that the European commission for standardization (CEN) currently provides no quantitative method for service life assessment of timber structures.

  6. 14. Fatigue Life Prediction in Service - A Statistical Approach

    Author : Thomas Svensson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fatigue life; sequential effects; variable amplitude fatigue; prediction uncertainties; variable amplitude fatigue;

    Abstract : This thesis treats the problem of fatigue life prediction. The emphasis is on the development of simplified methods, intended to be used in engineering design and the starting point is the established methods for fatigue prediction in service, namely the Wöhler curve, the Paris´ law and the Palmgren-Miner law of cumulative damage.
