Rehabilitation and strengthening of a hypar concrete shell by textile reinforced concrete
TRC (textile reinforced concrete) is suitable for strengthening of already existing concrete structures. The ultimate load bearing behavior as well as the serviceability can be increased significantly. In this paper some results of an investigation on a Hyperbolic Paraboloid Shell will be presented. The reinforced concrete shell with a thickness of 8 cm covers an area of 38 x 39m without any support. The actual state of the concrete shell was examined. Based on a FEM analysis a necessary strengthening method had to be planned. The strengthening layer is made of TRC, in which fine grained concrete is reinforced by several layers of textile reinforcement (e.g. carbon fabrics) with a polymer coating. This is the first practical application of TRC for strengthening. The paper covers information about architectural design, structural engineering design, constructive aspects, conception of reinforcement and manufacturing of the strengthening layer. Furthermore design engineering and experimental analysis including the issue of technical approval by the authorities are detailed.
