Abstract

This research examined the mechanical characteristics and failure patterns of ultra-high performance concrete (UHPC) pipe through trilateral loading test and numerical simulation. The test results provided critical data, including crack load, failure load, and load-displacement curves. The findings indicate that the crack load for the tested pipe is 232kN/m, the failure load is 452kN/m, the maximum horizontal displacement is 64.3mm, and the maximum vertical displacement is 71.6mm. During radial loading, four primary cracks and multiple secondary cracks emerged internally and externally on the left and right sides of the pipe top and bottom, ultimately leading to concrete spalling, reinforcing steel yielding, and compression zone concrete crushing. Using the test results, a finite element model for the trilateral test of the UHPC pipe was created using ABAQUS numerical software. When compared to the test results, the simulation results showed that the numerical method accurately predicted the macroscopic failure process and load-bearing capacity of the UHPC pipe.
