lattice dome

lattice dome

A steel dome structure having members which follow the circles of latitude and two sets of diagonals replacing the lines of longitude and forming a series of isosceles triangles.

As a new kind of spatial structure, the Suspen-Dome structure [1-3] offers advantages over either the single-layer lattice dome or the tensegric network and is gaining increasing usage.
To have a convenient cable arrangement, a single-layer lattice dome with parallel grid is adopted in the Suspen-Dome.
The Suspen-Dome was restrained vertically, radially, and latitudinally, at the 32 nodes of the outer ring of the single-layer lattice dome. In order to simulate the dead load, MASS21 element was built on each node of the single-layer lattice dome and the added-mass is 2000 kg.
The nodes of single-layer lattice dome number 137 and 32 nodes of these are constrained to three directions, while the remaining elements are 3D beam element with 6 degrees of freedom.
The third condition deletes the 32 struts and the 5 cables altogether, creating a single-layer lattice dome, while the node coordinates remain the same as the nodes of the single-layer lattice dome in Suspen-Dome.
