APPLICATION OF RULED SURFACES IN FREEFORM AND GEAR METROLOGY
Acta Polytechnica, 2021 An application of two ruled surfaces (i.e., surfaces generated by a motion of a straight line), a surface of hyperbolic paraboloid and a tangent surface of a cylindrical helix in freeform and gear metrology is introduced in this paper. Both surfaces have

Integrated Parametric Shaping of Curvilinear Steel Bar Structures of Canopy Roofs
Buildings, 2019 Shaping building objects is conditioned by many interrelated factors, both architectural and structural. Modern tools for shaping structures working in the environment of Rhinoceros 3D such as Grasshopper and Karamba 3D enable algorithmic-aided shaping ...

Hyperbolic Paraboloid Tensile Structure—Numerical CFD Simulation of Wind Flow in RWIND Software
Buildings, 2023 Tensile membrane structures combine a prestressed roofing envelope material and supporting elements. To design these structures, there is a set of recommendations in the European Design Guide for Tensile Surface Structures and some other national ...

The Markham Moor Papilio – A Picturesque Commentary [PDF]
The Open Arts Journal, 2014 This commentary on a little-known yet remarkable structure along the A1, originally built as a roadside petrol station with a canopy in the form of a hyperbolic paraboloid, demonstrates the affinity between the architecture of pavilions on the one hand ...
