  1. 11. Reliability-based assessment procedures for existing concrete structures

    Författare :Joakim Jeppsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; reliability theory; service life; assessment; monitoring; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Sammanfattning : A feasibility study of reliability theory as a tool for the assessment of present safety and residual service life of damaged concrete structures has been performed in order to find a transparent methodology for the assessment procedure. It is concluded that the current guidelines are open to interpretation and that the variation in the results obtained regarding the structural safety is too great to be acceptable. LÄS MER

    Sammanfattning : The ever-growing demand of wireless traffic poses a challenge for current cellular networks. Each new generation must find new ways to boost the network capacity and spectral efficiency (SE) per device. A pillar of 5G is massive multiple-input-multiple-output (MIMO) technology. LÄS MER
