Tyre Migration - Page 1 of 1 - International Cement Review
The normal maximum design ovality for a tyre is .2% relative to the inside diameter of the kiln shell. This would give a difference to 8 mm between the horizontal and vertical outside dimension on a tyre for a 4000 mm kiln. Under ideal conditions, this would result in a shell ovality of 0.23%, but in practice this is rarely achieved.

Braced frames - SteelConstruction.info
Braced frames. Braced frames are a very common form of construction, being economic to construct and simple to analyse. Economy comes from the inexpensive, nominally pinned connections between beams and columns. Bracing, which provides stability and resists lateral loads, may be from diagonal steel members or, from a concrete 'core'.
