Acoustic emission-based damage analysis of steel fibre reinforced concrete in progressive cyclic uniaxial tension tests KU Leuven
Although direct tension tests (DTT) on steel fibre reinforced concrete (SFRC) are difficult to perform, they are of interest because of the uniform tensile stress distribution. Therefore, this paper reports on 31 DTT under monotonic or progressive cyclic loading. All test specimens are notched and continuously monitored with acoustic emission (AE) sensors and clip gauges. The aim is a better understanding of the (cyclic) uniaxial tensile ...
Effect of pre-existing longitudinal and transverse corrosion cracks on the flexural behaviour of corroded RC beams KU Leuven
Assessing the residual capacity of corroded reinforced concrete (RC) beams depends on quantifying the corrosion cracks and rebar cross-section loss, and understanding their influence on the structural behaviour. Relations between corrosion crack widths and cross-section loss have been developed in the literature, and experimental studies have shown a decrease in the flexural capacity of corroded RC beams. However, their results were only related ...
Sectional analysis of the cyclic behavior of steel fiber reinforced concrete KU Leuven
Steel fiber reinforced concrete (SFRC) is known for improving the tensile post-cracking fatigue behavior of concrete. This paper presents a method to obtain the cyclic tensile behavior of SFRC through sectional analysis, using a limited amount of input parameters. The analytical model is divided into two parts: a monotonic and cyclic model. The monotonic model calculates the uniaxial stress-crack width curves or constitutive laws of SFRC that ...
