Autor: ANTON, Arturo; MEIJIDE, Antonio G.; CORBAL, Jesus J.
Resumen: A timber shell structure is designed to provide covering for an outdoor auditorium in
Madrid (Spain). The covering comprises five independent overlapped marquees with
similar shape but diverse dimensions. The surface geometry of each marquee is defined by a hyperbolic paraboloid, with its boundaries delimited by elliptical curves in horizontal
projection. Structural section for the timber shell is a composite section with several
staggered layers of straight sawn timber planks, arranged in two orthogonal directions
following the straight skew lines of the hyperbolic paraboloid. Over them two continuous
top layers are arranged which provides bracing for the structure and support for the
waterproofing material. Each layer is laid over the previous one, bolted and glued with
polyurethane adhesive. Special characteristics of the design analysis and detailed erection process are described. The designed solution provides lightweight roofing with a powerful and original image, short construction time and reasonable budget.
