Sinan Erdem Dome - Structure of The Building

Structure of The Building

Steel roof structure in a spherical shell form, spanning 112 m × 154 m (367 ft × 505 ft) plan dimensions and with two planar faces at each side overall forms a shuttle like geometry. Main loadbearing supports are 6 reinforced concrete twin columns with an r/c support mass which holds the tail section of the roof form. Head section of the roof is fixed to the existing structure.

Steel trusses have fix supports on top of twin columns. Top and bottom chords are made up of circular hollow sections which forms a triangular shape. Three main trusses and secondary circular girders resting on them build up the skeleton while trapezoidal steel sheet covers and completes the roof system. Steel roof and its supports are separate from tribune structure constituting an independent structure by itself.

Famous quotes containing the words structure and/or building:

    Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.
    Karl Wilhelm Von Humboldt (1767–1835)

    Are we not madder than those first inhabitants of the plain of Sennar? We know that the distance separating the earth from the sky is infinite, and yet we do not stop building our tower.
    Denis Diderot (1713–1784)
