Reliability of Structural Members Designed with the Eurocodes NDPs Selected by EU and EFTA Member States
The reliability level of structural members in buildings designed according to the Eurocodes was assessed for 20 EU and EFTA MS using the NDPs uploaded in the European Commission NDPs Database by the end of 2017 by 16 EU MS and consulting the National Annexes of four other EU and EFTA MS.
The main conclusions of the study are the following:
- the reliability of structural members which were designed according to the national choice of the NDPs varies in a rather broad range. The reliability levels of the structural members for most common categories of imposed loads match the reliability indices recommended in EN 1990.
- in some cases the reliability levels according to the country choices of the NDPs are below the CEN target values and therefore should be further analysed and calibrated.
- the reliability levels achieved using CEN recommended values should also be studied further, in order to delineate eventual needs for calibration of the recommended values.
- the reliability levels of composite, steel and timber members designed according to the lower bound of imposed loads recommended in EN 1991-1-1, are commonly lower than the reliability levels recommended in EN 1990 for some fundamental combinations of actions.
It should be noted, that the reliability of whole structure is normally higher than the one of a structural member. Thus, the presented results show that a generally good level of structural reliability has been achieved with the country choices of the NDPs.
