  2. Skeleton frames: Assembling Chris Gorse, Joseph Kangwa and Ian Dickinson These slides should be read in conjunction with Emmitt, S. and Gorse, C. (2010) Barry’s Advanced Construction of Buildings. Oxford, Blackwell Publishing

  3. Multi-story skeleton frame

  4. Skeleton frames • The following drawing shows a three dimensional view of a steel frame

  5. Actual frame

  6. The completed building

  7. precaststairs are provide a fast and safe installation into the steel frame

  8. Lining the building up • The building will twist slightly as it is erected. Before casting any concrete any movement in the structure needs to be corrected. Winches are used to pull the building back in line.

  9. As the building is erected it will need to be pulled into line.

  10. Bracing • Triangulation and solid infill walls are used to hold the structure rigid and resist horizontal loads such as wind.

  11. Wind bracing

  12. Roof bracing and composite floor provide lateral resistance against wind loads

  13. Fixing the frame together

  14. Roof beam to column connection • Beam to column connection

  15. Universal column Column prefabricated with end plate All holes for bolts are accurately predrilled off site Splice plate bolted to both top and bottom column End plates welded to the end of each column and bolted together Column to column – spliced and bolted connection

  16. Splice fixing ready to receive next column

  17. Column to column splice fixing

  18. Base plate welded to column (plate minimum 12mm thick) Steel packing shims fix column at correct level Temporary bund wall (sand) None shrinkable grout fills void left below plate (liquid grout poured into voids) Void formed by cardboard or polystyrene cones, which allows +/- 20mm horizontal tolerance is filled with grout Large washer fixed to bolt to prevent pull out Steel wedge holds the base in the correct line (position) Column base and holding down bolts

  19. Holding down bolts cast in concrete

  20. Holding down bolt in temporary frame which would be cast into a concrete base

  21. Universal column Beam prefabricated with end plate welded to the beam. End plate Holes for bolts predrilled in column and beam end plate ensuring accurate fixing Beam connection using end plates welded to the beam

  22. Beam to column connection
