Practical Aspects of the Design and
Construction of a Small Cable Roof Structure

Abstract
Cable roof structures have only become widespread in large span structures in
the latter part of the twentieth century. However, they still represent a rel
a-
tively new form of roof construction, especially
as in the present case of a
small span innovative structural solution.
The contribution of this text to the
structural engineering community lies in the increased interest in build
ing
simple cable roof structures. Si
nce its completion in September 1996, this
small cable roof structure has been recognized as an interesting architectural
and structural example. The text describes aspects of the design and constru
c-
tion of a small cable roof that was designed as a roof for an open-
air theater
stage for the city of Sao Jose do Rio Pardo, Sao Paulo, Brazil. A cable network,
in the shape of a hyperbolic paraboloid surface, is anchored in a
reinforced
concrete edge ring. The projection of the ring’s axis onto the ground plane is
an ellipse. Workers with specialized training were employed in the various
stages of the construction, which was completed in September 1996.

1. Introduction
The cable roof network, initially in the form of a hyperbolic paraboloid surface,
is anchored in a ring of reinforced concrete whose axis projects an ellipse in the
horizontal plan. The larger and smaller axes of the ellipse measure 20.00 m and
13.00 m, respectively. The network is formed by an orthogonal mesh 10 by 6,
which is parallel to the ellipse axes. Both end points of the larger axis are 1.75 m
below the surface center, while both end points of the smaller axis are 1.00 m
above the surface center. The center of the surface is 4.50 m above the ground. A
