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

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

    Sammanfattning : 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. LÄS MER

  3. 2. LCA and LCCA in the design of geotechnical engineering works

    Författare :Ida Samuelsson; Stefan Larsson; Johan Spross; Rasmus Rempling; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; Life Cycle Cost Analysis; climate impact; costs; geotechnical engineering; Livscykelanalys; Livscykelkostnadsanalys; klimatpåverkan; kostnader; geoteknik; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Geotechnical engineering works are part of almost all construction and infrastructure projects. The geotechnical engineering work contributes to the impact on the environment and gives rise to costs throughout its life cycle. LÄS MER

    Författare :José Javier Veganzones Muñoz; Costin Pacoste; Raid Karoumi; Lars Pettersson; Rui Vaz Rodrigues; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Overhang slab; Edge beam; Life-cycle Cost Analysis; Non-linear FE-analysis; Design methods; Shear force; Failure mode; Effective width; Minimal width.; Konsolplattor; Kantbalkar; Livscykelkostnadsanalys; Icke-linjär FE-analys; Dimensioneringsmetoder; Tvärkrafter; Brott; Fördelningsbredd; Minimal bredd.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Bridge edge beams are associated with high life-cycle costs because of the need of maintenance, which also causes traffic disturbances. For this reason, the Swedish Transport Administration started a project to find better solutions. One of the proposals was a design without edge beam. LÄS MER

  5. 4. Performance Measures of Road Infrastructures

    Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
