  1. 1. Analyzing a New Method for Estimating Strength Classes in Existing RC Structures

    Master-uppsats, KTH/Transportplanering

    Författare :Gabriel Matli; Veronica Soulaka; [2023]
    Nyckelord :;

    Sammanfattning : This master thesis focuses on validating the Graphical Concrete Strength Class (GCSC) method on a large scale. The GCSC method is an empirical approach for assessing the concrete strength class of existing reinforced concrete structures. LÄS MER

  3. 2. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken

    Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanik

    Författare :Zeinab Mirzahassanagha; Eva Malo; [2021]
    Nyckelord :CFRP; External Strengthening Method; RC Bridges; Curved Substrate; Finite Element Modelling; Kolfiberväv; Extern Förstärkningsmetod; Betongarmerade broar; Konkav yta; Finita Elementa Modellering;

    Sammanfattning : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. LÄS MER

  4. 3. RC Trough Bridges: A Parametric Study using FEM and an Analysis of their Current State

    Sammanfattning : There are approximately 4000 railway bridges in Sweden managed by the Swedish Administration of Transport (Trafikverket), of which a common construction type is the reinforced concrete (RC) trough bridge, which is a structure that consists of a slab carried by two longitudinal main beams which transfer loads towards the supports. A substantial amount of the RC trough bridge population is approaching the end of their service lives which consequently implies that the replacement of some of these bridges can be expected in the near future.
