To examine how different compositions and shapes of steel fibers influence the mechanical responses damage behavior ultra-high performance concrete (UHPC), several axial compression tests are performed. The impact fiber on acoustic emission (AE) parameters UHPC is studied based AE technology. variation law during evolution qualitatively analyzed. According to development trend energy cumulative energy, level specimens quantitatively investigated. constitutive equation established energy. results show that beneficial strength ductility UHPC. accumulative ringing count a similar growth rule with strain have good correspondence stress-strain curve. model fits well test data, which can analyze under compression.
