Steel Fibre Concrete for Underwater Slabs at Potsdamer Platz
Abstract:Potsdamer Platz in Berlin is the site of a 70,000 m² development that is creating a new city center, with a myriad of offices, housing, shops, entertainment and recreational facilities. As most of the buildings reach far below the groundwater level, the construction of deep building pits is necessary. Due to underground conditions and environmental protection requirements, sealing injection layers can not be used for the deeper parts of these building pits. The remaining solution is to construct an underwater concrete slab, back anchored by tension piles. These building pits are irregularly shaped, with extremely high water pressure on the concrete slab. In order to increase overall safety, steel fibre concrete has been used to achieve a robust and ductile construction.

Structural Engineering International (SEI), the quarterly Journal of IABSE, published since 1991, is the leading international journal of structural engineering dealing with all types of structures and materials. SEI offers its readers a unique blend of short profiles on recent structures, and longer, in-depth technical articles on research, development, design, construction and maintenance. Articles are written by practicing engineers and academia from around the world and reflect the high standards of IABSE. IABSE Peer Review stamps are given to papers that have passed through a highly selective review process and demonstrate a significant contribution to the state of structural engineering knowledge.To recognise contributions of the highest quality, an Outstanding Paper Award is presented each year.
SEI is printed in Switzerland; ISSN 1016-8664; E-ISSN 1683-0350
