Abstract: 
In the city center of Vienna there are still a large number of reinforced concrete structures in use which were built with ribbed reinforced concrete slabs during the first decades of the twentieth century. While the load carrying capacity of these slabs in bending is in accordance with contemporary structural standards, the shear carrying capacity does not always reach the level required today. The paper reports on experimental load carrying tests on 100 year old reinforced concrete slabs. Moreover, the practicability and performance of reinforcing measures were checked. It can be shown that the shear carrying capacity of these slab systems is smaller than the load carrying capacity in bending. A method for the strengthening of these slabs is presented. Destructive load tests on strengthened slabs have demonstrated the practicability of the proposed strengthening method.
