To explore the compression behavior of ultra-high-performance concrete (UHPC) confined with rectilinear ties, sixty specimens were tested under axial compression. The investigated parameters included the compressive strength of UHPC in the range of 84.72–155.45 MPa, the volumetric ratio of rectilinear ties in the range of 0.9–2.0%, and the yield strength of rectilinear ties in the range of 873–1215 MPa. The failure modes of specimens were the formation of an inclined shear failure plane. The axial stress–axial strain curves and the axial stress–lateral strain curves of confined UHPC were analyzed. Besides, the effects of investigated parameters on the load-bearing capacity and ductility of confined UHPC were analyzed. Moreover, the prediction models for the lateral strain of rectilinear ties at peak stress, load-capacity and ductility of confined UHPC were developed.
