In particular, the retrofitting of the protected ribbed slabs is one of the main challenges which requires special strengthening provisions. These slender structural elements, featuring smooth reinforcing bars with end hooks and no stirrups, show several deficiencies regarding their structural and fire safety. Since the ribbed slabs cover an area of approximately 4\u2019300 m<sup>2<\/sup> of the building floors\u2013 with a total of about 1\u2019200 ribs\u2013 an individual strengthening of each rib was not economic and time-efficient and therefore out of question. Instead, a novel reinforcing solution with Ultra-High-Performance Fibre Reinforced Concrete will be applied. A thin 40 mm overlay of UHPFRC above the existing ribbed slab at the critical areas is enough to fulfil the current requirements of the Swiss Standards.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The conversion of the historic office building Du Pont in the heart of Zurich is one of the most complex renovation projects which is currently being undertaken by our engineering team.
