Zhao-Hui LU, Hong-Jun WANG, Fulin QU, Yan-Gang ZHAO, Peiran LI, Wengui LI

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 4,   Pages 888-906 doi: 10.1007/s11709-020-0637-0

Abstract: In this study, a total of 177 flexural experimental tests of corroded reinforced concrete (CRC) beamsThrough this database, the effects of various parameters on the flexural capacity of CRC beams were discussedbeams, while other parameters have much less effect.In addition, six available empirical models for calculating the residual flexural strength of CRC beamsbeams confirmed by the comparisons.

Abstract: ductility in this material and the quasi-brittle behavior of concrete, FRP-reinforced concrete (FRP-RC) beamsBecause the limited deformation capacity of FRP-RC beams depends on the ductility of their compressionA control beam and four beams with different PCCBs were cast and tested under four-point bending conditionsThe goal was to find an appropriate PCCB for use in the compression zone of the beams, which not onlyimproved the ductility but also changed the failure mode of the beams from shear to flexural.
