| Abstract: |
The office building housing in Windisch was fully renovated and also raised by one storey in the summer of 2011. In addition the buildings seismic resistance was also increased. The initial calculations of the structure’s earthquake resistance indicated that only 10% of the earthquake resistance required by the latest standards could be guaranteed without additional strengthening of the structure. The strengthening System which was used was the StressHead CarboStress System which involved the installation and post-tensioning of Sika CarboDur CFRP plates. In total, 16 of these post- tensioned plates with a tensioning force of 220kN were used. The anchorage of the tensioning force was achieved with a combined CFRP StressHead and steel reaction frame to transfer the load directly into the floor slabs. |
