WebFinally, a simplified inverse analysis is proposed for the ring-on-ring test based on the elastic slab bending and yield line theories. The calculation results indicate a 19% lower tensile elastic limit stress of the UHPFRC, while an almost equivalent value of tensile strength is obtained from the ring-on-ring test, compared with the 4PBT results. Web1 May 2016 · This paper presents experimental results on creep and relaxation of UHPFRC at early age (3–8 days), under low to high tensile stresses (1.2, 2.7, 5.4, and 8.1 …
