Parabolic Hyperboloid Roof

He is celebrated for his feats of architectural engineering that transform concrete into visual poetry with his structural design based on hyperbolic paraboloid geometric form.

The hyperbolic paraboloid is a doubly ruled surface so it may be used to construct a saddle roof from straight beams. A roof having the shape of a geometric figure called a hyperbolic paraboloid. In this position the hyperbolic paraboloid opens downward along the x axis and upward along the y axis that is the parabola in the plane x 0 opens upward and the parabola in.

A hyperbolic paraboloid not to be confused with a hyperboloid is a doubly ruled surface shaped like a saddle in a suitable coordinate system a hyperbolic paraboloid can be represented by the equation.
