Reinforced concrete, buildings design references

For instance, the Greek code (KANEPE 2012) for strucmral interventions on reinforced concrete buildings, after harmonization with Eurocode 8 Part 3, defines two hazard levels. The first has probability of exceedance of 50 % (maximum tolerable) in 50 years and corresponds to an average return period of 70 years, while the second has a probability of exceedance of 10 % in 50 years that corresponds to a 475 years return period. For the 10/50 level, the design seismic action of EC8 Part 1 is taken into account, while for the 50/50 level, 60 % of the design seismic action of EC8 Part 1 is taken into account. It is also stated that a Public Authority shall define the cases where a 50 % probability of exceedance within the reference 50-year period will not be allowed. 

DIN EN 14879-1 (supersedes VDI 2532) [18] applies to the design and execution of metal constructions to be protected against corrosion. For buildings of reinforced concrete, or concrete and brickwork, VDI 2533 [19] are valid. DIN EN 14879-4 (supersedes VDI 2537[20]) [16] deals with surface protection with layers of natural and synthetic rubber. VDI Guidelines should be referred to in the selection and treatment of the material base for the process industries such as metal and concrete structures and fabrications, as well as in the selection and properties of the protective material, namely rubbers). 

In Italy, the decree nr. 3274 May 2005, concerning the technical regulations for the design, evaluation, and seismic adjustment of buildings, introduces the use of FRP for the seismic strengthening of reinforced concrete (r.c.) manbers and specifically refers to the instructions of CNR-DT 200/2004 for the safety assessments.
