“…The corresponding calculation formulas for the local bearing capacity were provided. However, Zhou et al [19][20][21][22] determined the local compression behavior of steel fiber-reinforced reactive powder concrete (SFR-RPC), reinforced with orthogonal ties or spirals under concentrated loads. The study found that the high-strength spirals (f yv = 1027 MPa) in most specimens could not reach the yield strength when the specimens reached the peak load.…”

The local bearing strength and deformation capacity of the reactive powder concrete (RPC) specimens can be dramatically improved by arranging steel spirals. In effect, the actual stress level of spirals is closely correlated with the compression behavior of concrete loaded over limited area. However, limited work has been focused on the actual stress of steel spirals in RPC. To obtain the actual confinement provided by the high-strength spirals in anchorage zones, 10 RPC specimens loaded over limited area were conducted. The loadspiral strain relationships and the deformation-spiral strain responses were discussed to investigate the lateral response of RPC. The high-strength spirals failed to reach the yield strength at the peak load, and the actual strain of the spirals ranged from 1800 to 2500 με, while the residual strength of the highstrength spirals could be fully utilized after the peak load. The actual stress of
