Steel concrete composite bridges

  1. 1. PREFACE I see this book as a journey. A journey of experience from the first simple river crossing to the more complex suspended spans of today. A journey across the world… through to the countless bridges today that perform their task with pride, and always marvelling at how we build so strong, always questioning.
  2. 2. Chapter 0 Introduction to Eurocodes “… Eurocodes with their 10 volumes some of these with 18 parts, each with their own National Annex, some with 370 separate clauses or sub clauses, amounting to some 5000 sheets of paper, can seem a daunting document.”
  3. 3. Chapter 1 General concepts “ the composite whole being substantially stronger and stiffer than the sum of the parts…”
  4. 4. Steel-concrete composite structures are a common and economical form. This book initially reviews the forms of structure in which composite construction is used, and then each of the more common forms of composite construction is considered in more detail.
  5. 5. Chapter 2 Simple beam bridges “estimation of flange size assumes that the flanges will primarily carry the moments with only a small contribution from the web..”
  6. 6. Figure 2.2 Layout of Bridge for Example 2.1
  7. 7. Chapter 3 Integral bridges “integral bridges are used for all bridges up to 60 m long …..”
  8. 8. a) b) Figure 3.1 Example 3.2 maximum and minimum soil pressure; b) bending moments on the portal.
  9. 9. Chapter 4 Continuous bridges “the key benefit of continuity is a reduction (or elimination) of bearings and joints…”
  10. 10. Chapter 5 Viaducts “..the most efficient form of structure is a two girder system…”
  11. 11. Chapter 6 Haunches and double composite action “a double composite structure … providing composite action to both the top and bottom flanges ..”
  12. 12. Chapter 7 Box Girders “.. a triangular structure .. is stiffer and less susceptible to distortion than the conventional … forms…”
  13. 13. Chapter 8 Trusses “the simpler truss types ... with linked bracing between bays of bracing that is directly in line give the best forms..”
  14. 14. Chapter 9 Arches “sculpting bridges ..”
  15. 15. Chapter 10 Cable stay bridges “..have a system of forces that are resolved within the deck-stay-tower system..”
  16. 16. Chapter 11 Prestressed steel-concrete composites “for the composite section with corrugated webs.. the reduction in dead load and section area will lead to a reduction in prestress..”
  17. 17. Chapter 12 Assessment of composite bridges “sometimes we underestimate the full range of ways a structure can behave”
  18. 18. APPENDIX Appendix A Appendix B Appendix C Appendix D Appendix E Appendix F Appendix G Approximate methods Calculation of elastic section properties Section properties for examples Calculation of plastic section properties Calculation of torsional section properties Calculation of double composite section properties Moment axial load interaction for compact steelconcrete composite section
