RIBBED DOME Russian patent published in 2007 - IPC E04B7/08 E04B1/32 

FIELD: construction, particularly dome covering structures.

SUBSTANCE: dome comprises meridional arch-shaped ribs of load- articulated bearing members connected with each other and rigid baulks fastened to meridional arch-shaped ribs in load-bearing member connection points so that annular load-bearing members are formed over dome surface. The annular load-bearing members divide each dome sector into trapezoid and upper triangular sections. Additional stiffening members are rigidly connected to each trapezoid section. The additional stiffening members are made as quadrilaterals constituted of rods. The quadrilaterals are arranged over dome surface in staggered order and corners of each quadrilateral are connected to centers of corresponding rigid baulks and load-bearing members defining trapeze sides.

EFFECT: increased rigidity and provision of uniform load distribution over dome surface, improved load-bearing ability.
