Title (EN) PRESTRESSED COOLING TOWER
(FR) TOUR DE REFROIDISSEMENT PRECONTRAINTE
Abstract: front page image
(EN)Structure of flexible tensile members which requires only two arrays of said members (4, 6) for obtaining lateral stiffness of said structure, the ends of each member (4, 6) being attached to contour elements (8, 18, 30 or 32) and the members of each array having opposite curvatures for forming an axisymmetric geodesic network which is a section of a surface of revolution. The members of both arrays (4, 6) are prestressed and said network is geometrically arranged to be torque-balanced within said contour elements.
(FR)Structure de membres flexibles elastiques ne necessitant que deux rangees desdits membres (4, 6) pour obtenir la raideur laterale de ladite structure, les extremites de chaque membre (4, 6) etant rattachees a des elements de contour (8, 18, 30, ou 32) et les membres de chaque rangee present des courbures opposees afin de former un lacis geodesique symetriquement axial lequel est une section d"une surface de rotation. Les membres de chaque rangee (4, 6) sont precontraints et ledit lacis est geometriquement positionne afin d"etre equilibre en couple a l"interieur desdits elements de contour.
