Best Paper Presentation Award for Homam Spartali
The 13th fib International PhD-Symposium in Civil Engineering took place as an online symposium from 26th to 28th August 2020. At the closing ceremony, Homam Spartali received the "Best Paper Presentation Award" for his contribution "Bond behavior between high strength concrete and steel reinforcement under high cycle fatigue push-in loading" in the category "Structural Analysis and Design".We congratulate Homam on his success!
Reconstruction of the Rheinsteg with carbon concrete
The innovative material carbon concrete is used for the reconstruction of the Rheinsteg near Albbruck. The reinforced concrete slab of the 200 m long foot and cycle path bridge from the 1930s on the border between Germany and Switzerland showed severe corrosion damage and had to be demolished. As a replacement, a carbon concrete slab of similar thickness will be installed without any additional coating, so that the tare weight of the structure will not increase and the existing colummns and steel beams in the main load-bearing direction can continue to be used after a basic renovation. The Institute of Structural Concrete of the RWTH Aachen University carried out experimental and theoretical investigations on behalf of the company solidian GmbH and the client, the Rheinkraftwerk...
Sandwich elements made of high-performance materials for wide-span roof elements - transfer project
During the project funded by the German Research Foundation (DFG) for the development of sandwich elements with thin surface layers of carbon concrete, the first of four test specimens was successfully produced in the last few weeks. Despite the current circumstances, the 8.2 m long specimen could be concreted and prestressed with strands of carbon fibre plastic (CFRP). The two concrete layers required for the sandwich element were not produced horizontal, instead they were standing upright on the long side. This enabled the simultaneous production of the two layers and reduced the amount of further work. After the concrete hardened and the prestressing force had been induced, the insulating material was set between the two concrete layers. In this case, a polyurethane insulation...
