Case Study 

Earthquake reinforcement of masonry with S&P CFK-Laminates and S&P G-Sheet (FRP 2013_06)

Solution 

As part of a total renovation regarding earthquake resistance, this protected monument has been reinforced to meet norms. The statics calculations showed that various masonry walls need to be reinforced over several storeys. Vertically prestressed S&P CFK-Laminates transfer dynamic earthquake loads into the foundations. Diagonal CFK laminates transfer horizontal loads in the new slabs through a “gusset plate”. The G-Sheet AR 50/50, installed in advance, reinforces the old stone masonry and holds it together. The epoxy resin S&P Recisem is used to ensure vapour diffusion.

Material 

approx. 340 metres S&P CFK-Laminates and 200 m2 S&P G-Sheet AR 50/50
