Proposal for the fatigue strength of concrete under cycles of compression

We've recently published a paper in Construction and Building Materials, titled "Proposal for the fatigue strength of concrete under cycles of compression". This paper is based on the research I did during summer 2014 in Delft, to develop a proposal for the Dutch National Annex to the Eurocode.

You can download the paper for free following this link until March 1, 2016.

The abstract of the paper is:

The Dutch National Annex to Eurocode 2 deviates from Eurocode 2 for the W√∂hler curve for concrete in compression, but has a discontinuity in the S–N curve for 1 million load cycles. Therefore, a new expression for concrete subjected to repeated loading is sought, which should be valid, yet not overly conservative, for high strength concrete. A database of experiments on high strength concrete tested in compressive fatigue is developed, and used to derive new expressions. Two new formulas are proposed: (1) for the assessment of the fatigue strength of existing structures, and (2) a simplified method for
