FEATURE REINFORCED POLYMER HANGERS World's First Large Bridge Fully Relying on Carbon Fiber Reinforced Polymer Hangers Urs O. Meier EMPA, Swiss Federal Laboratories for Materials Science and Technology Ueberlandstrasse 129, Dübendorf Andreas U. Winistörfer Carbo-Link AG Undermülistrasse 25, Fehraltorf Lorenz Haspel sbp schlaich bergermann partner Schwabstrasse 43, Stuttgart ABSTRACT T he Public City Transport Operator (SSB) of Stuttgart is building in 2020 a network arch bridge of 124-meter span with carbon fibre reinforced polymer (CFRP) hangers. The use of CFRP for all hangers allows a reduction of the cross sectional area of those to about one quarter of an equivalent steel cross-section. The sustainability of the CFRP hangers is in comparison to those of steel impressive. Finally, the use of hangers made of CFRP is less expensive than of steel and gives more freedom for an aesthetic arrangement of the network. 22 | SAMPE JOURNAL | J A N UA R Y/ F E B R UA R Y 2 0 2 1 w w w. s a m p e . o r ghttp://www.sampe.org
