Description:

This study focuses on the energy dissipation characteristics of High-Performance Concrete (HPC) under uniaxial repeated compressive loading for three different grades. The objective is to analyze the energy dissipation capacity of HPC by examining the stress-strain hysteresis during repeated loading. The dimensionless energy dissipation ratio, Rn, quantifies the energy dissipated per loading-unloading cycle, depicting the proportion of dissipated energy relative to the total stored strain energy in each cycle. The present work includes the relationship between Rn and the normalized envelope strain at the peak of each cycle, as well as the normalized plastic strain at unloading. The results highlight the behavior of the Rn ratio. The findings indicate that all three grades of HPC investigated exhibit similar energy dissipation patterns. The plotted data reveal a bilinear behavior, characterized by an initial high rate of increase in Rn followed by a relatively slower rate of increase. Additionally, simple empirical relationships based on the observed data are also proposed. The results of this study can aid in determining elastic limits and damage indicators for HPC under repeated loading, enabling engineers to predict material behavior and optimize the design and maintenance of HPC structures in seismic and cyclic loading conditions. The results can be used for designing HPC structures capable of withstanding seismic and repeated loading conditions, enhancing their resilience and safety.
