Cable-Stayed Structure
Amiya has always experimented and successfully implemented innovative roof structures. They have put old wine into new bottles by reapplying the age-old roof-building system of cable-stayed cantilever roof structures, to innovative architectural concepts. This method of cantilever roof structures is being used increasingly in the construction of sports stadiums around the world. The multiple advantages of tubular or angular pre-fab structures are:

• Stability against wind uplift

Erection procedure of cable-stayed structures:

• Concrete columns are placed longitudinally at
    5.0M intervals

• 10M structures are projected in the front and
    5M projected at the back.
• To prevent overturn against Dead Load and live
    Load 2 16-diameter galvanized cables with steel
    core with 3mm PVC cover are fastened to the
    end of the tubular lattice girder
• To provide stability against wind uplift, the end
    of longer sides of the tubular girder are
    fastened
• Similar arrangements are made at end of shorter
    side by fastening 2 cables at the end and
    anchoring with the floor beam of other building.

Construction of cantilever cable-stayed structures for stadium:

• Depending on number of spectators to be
    accommodated, the configuration is either fully
    circular or with two parallel sides with ends
• The main columns supporting the cross girders
    are anchored at the rear end by steel cables
• The cross girders are of latticed tubular
    construction of 20M projection in front and
    about 5M at the back
• The rear portion of the roof of length about 15M
    are covered at the top and front 5.0M in front
    have sheet underneath the structures
• The sheets are troughed colour coated
    Galvalume sheets

Typical Applications:

• Sports Stadium
• Canopy
• Bridges
