2. 1. 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

4. 2. I-girder Composite Bridges with Lateral Bracing : Improved load distribution

   Author : Victor Vestman; Peter Collin; Robert Hällmark; Hans Petursson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; bridge; composite bridge; steel-concrete composite; I-girder; case study; horizontal trusses; lateral bracing; rehabilitation; strengthening; torsional stiffness; upgrading; Byggkonstruktion; Structural Engineering;

   Abstract : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. 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. Soil-Steel Composite Bridges : Research advances and application

   Author : Amer Wadi; Raid Karoumi; Lars Pettersson; Ian D. Moore; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible culvert; Soil‒steel composite bridge; Sloping terrain; Swedish design method; Finite element model; Ultimate capacity; Avalanche load; Failure load; Low soil cover; Failure mechanism; Long-span; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : Soil-steel composite bridges are considered competitive structures being an economical alternative to similar span concrete bridges. This frequently stimulates practitioners to push their design limits and expand the different areas of application including their performance in sloping terrain. READ MORE

7. 5. Development of connections for fibre reinforced bridge elements and an analysis of sustainability

   Author : Valbona Mara; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge; insert; connection; deck; FRP; bolt; joint; fibre reinforced polymer; LCC; LCA;

   Abstract : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. READ MORE
