Domes — Geometrica
Lamella: Lamella domes are generated with concentric rings, where each subsequent ring is rotated by a half module. This reduces the length of the ring tubes as the geometry proceeds towards the apex. ... As with Lamella domes, the horizontal Kiewitt rings provide an easy check during construction, but the pattern results in many more different ...
Lamella Structure | Lexicon | DERIX
Combined lamella construction for beams in bending In the case of bending beams, a combined construction using lamellas of different grading classes is possible. Higher strength class lamellas are used at the tension edge, while lamellas of the next lower strength class are used in the interior or at the compression edge.

environmental impacts. Construction activities disturb areas, remove vegetative cover, and expose soils to runoff, thus becoming an important source of pollution. Construction sites have measured erosion rates of approximately 20 to 200 tons per acre per year (Pitt et al. 2007). Construction operations may increase
The lamella roof.
Lamella roof construction may take the form of a two- or three-hinged arch, the horizontal thrust being absorbed by tie-rods, or buttresses carrying it to the foundations. Its principal advantage is the clear uninterrupted span it affords from side to side of the enclosure. On account also of its low cost, simplicity and ease of erection and ...
