Architect John Pawson retrofitted the 1960s building with a library and galleries for temporary and permanent installations over five soaring floors, while keeping the

hyperbolic paraboloid roof.

Later chapters are devoted to design, calculation methods, and materials selection for five types of spatial concrete structures: convex translation shells with positive Gaussian curvature, long convex cylindrical shells,

hyperbolic paraboloid shells, domes, and long reinforced concrete folders.

Florentino used the

hyperbolic paraboloid concept, which allows each house to withstand up to an intensity-8 earthquake and wind velocity of up to 275-km per hour.

And what a roof it is--a complex copper clad

hyperbolic paraboloid structure that Mace's associate director Jonathan Emmines refers to affectionately as the 'Concrete Pringle' or 'Witch's Hat'.

The

Hyperbolic paraboloid house, a design which was developed by architect E.

which is readily classified as a

hyperbolic paraboloid with a vertex centred at (m, n, p).

Our logo has been refurnished to model the most familiar sight in the Campus, the Dogra roof- the

hyperbolic paraboloid, which is central to innovation and technology at IIT Delhi.

Hyperbolic paraboloid surfaces were considered in order to simplify the structural estimation and construction, and at the same time, giving a slender configuration and brightness to the form.

For the Commonwealth Institute he adopted the then-fashionable form of a

hyperbolic paraboloid, a complex, double-curving surface pioneered by the brilliant Spanish-born engineer-architect Felix Candela (1910-97) which had never before been attempted in Britain.

A rare example in the history of music when a building was designed for the performance of a specific piece of music, "Poeme Electronique" was performed in a structure designed by Xenakis (who doubled as an architect) based on the complex mathematical surface of the

hyperbolic paraboloid.

The library's saw-tooth roof is also a response to built context, amplified here with playful interlocking arrangements of high and low gables that produce

hyperbolic paraboloid sections.
