In particular, this paper analyzes the variations in the residual tensile strength of steel fiber-reinforced concretes following cyclic flexural loading, which causes a predefined level of damage. To do so, a total of 40 prismatic specimens were tested. The specimens were not notched, but had previously been subjected to precracking. This has a similar effect to notching, but with a much smaller radius around the edge of the crack, which is therefore more vulnerable to fatigue. The results show that the damage provokes a progressive reduction in the residual traction strength. The study proposes two numerical expressions for the stress–crack width softening curves under tensile loads: an exponential formulation and a potential formulation. In both cases, the coefficients of both formulations depend on the damage that is induced. In addition, the proposal is to use fitted curves of the above-mentioned potential type. application/pdf eng Wiley Structural Concrete. 2017, V. 19, n. 2, p. 340-351 https://doi.org/10.1002/suco.201600102 Fatigue Fiber-reinforced high-strength concrete High-strength concrete Residual tension strength Ingeniería civil Resistencia de materiales Civil engineering Strength of materials Postcracking residual strengths of fiber‐reinforced high‐performance concrete after cyclic loading info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion info:eu-repo/semantics/openAccess Structural Concrete 19 2 340 351 THUMBNAIL Gonzalez-sc_2017.pdf.jpg Gonzalez-sc_2017.pdf.jpg IM Thumbnail image/jpeg 3390 https://riubu.ubu.es/bitstream/10259/8660/3/Gonzalez-sc_2017.pdf.jpg 157fe6dc5e1ed3fba3afd463ed3cf43a MD5 3 Gonzalez--sc_2017.pdf.jpg Gonzalez--sc_2017.pdf.jpg IM Thumbnail image/jpeg 4252 https://riubu.ubu.es/bitstream/10259/8660/5/Gonzalez--sc_2017.pdf.jpg 4ed75cefc01982628dfe5a473da8d164 MD5 5 LICENSE license.txt license.txt text/plain; charset=utf-8 999 https://riubu.ubu.es/bitstream/10259/8660/2/license.txt b295bcbce42e2caabeb0c623d3860c06 MD5 2 ORIGINAL Gonzalez--sc_2017.pdf Gonzalez--sc_2017.pdf application/pdf 2464129 https://riubu.ubu.es/bitstream/10259/8660/4/Gonzalez--sc_2017.pdf acc2a44e9ced49a5f572c41e048543ef MD5 4 10259/8660 oai:riubu.ubu.es:10259/8660 2024-02-13 02:05:20.001 Repositorio Institucional de la Universidad de Burgos bubrep@ubu.es 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
