  2. 1. Slab Frame Bridges : Structural Optimization Considering Investment Cost and Environmental Impacts

    Author : Majid Solat Yavari; Costin Pacoste-Calmanovici; Raid Karoumi; Mario Plos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slab frame bridge; Structural design; Cost optimization; Optimization of environmental impact; Life cycle assessment; Genetic algorithm; Pattern search method; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : This research encompasses the automated design and structural optimization of reinforced concrete slab frame bridges, considering investment costs and environmental impacts. The most important feature of this work is that it focusses on realistic and complete models of slab frame bridges rather than on optimization of only individual members or sections of a bridge.

  4. 2. Composite Bridges : Innovative ways of achieving composite action

    Author : Robert Hällmark; Peter Collin; Ian May; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite action; bridges; steel; concrete; shear connectors; prefabrication; coiled spring pins; shear studs; post-installation; design guidance; Structural Engineering; Konstruktionsteknik;

    Abstract : The topic of this thesis is steel-concrete composite bridges and innovative ways of achieving composite action. The typical superstructure consists of three main components: the steel girders, the concrete deck slab and the shear connectors. READ MORE

  5. 3. Prefabricated composite bridges : a study of dry deck joints

    Author : Robert Hällmark; Ian May; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge construction; prefabrication; monitoring; Steel Structures; Stålbyggnad;

    Abstract : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.

  6. 4. Assessment of Concrete Bridges : Models and Tests for Refined Capacity Estimates

    Author : Niklas Bagge; Anders Carolin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Optimising the strategy for repairing, upgrading and replacing bridges in the European Union, and elsewhere, is becoming increasingly important due to ageing of the bridge stock, continuously increasing load requirements and budgetary limitations. Thus, there is a clear need to identify or develop, and implement, refined methods for assessing existing bridges in order to determine the most cost-effective options and actions to extend their lives, increase their capacities or replace them.

  7. 5. Load carrying capacity of bridges : three case studies of bridges in northern Sweden where probabilistic methods have been used to study effects of monitoring and strengthening

    Author : Anders Stenlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Probabilistic methods are presented for the assessment of bridges. Load carrying capacity calculations and evaluations of strengthening methods are carried out for three road bridges in northern Sweden: 1) The E4-bridge over Pite River - A four span steel beam bridge with a concrete deck built in 1969.
