A Review of Three Common Concrete Multiaxial Strength Criteria from 2010 to 2020

Strength criterion is fundamental to the study of the strength assessment and design of engineering structures under complex stress conditions. Through experiments with a range of concretes, a large number of multiaxial strength criteria have been proposed to date, with many new developments from 2010 to 2020.Even so, there has been minimal comparative analysis of the research results of different strength criteria. This paper presents a comparative analysis of the strength criteria of ordinary concrete, high-performance concrete and lightweight aggregate concrete from the past 10 years. First, the classic concrete strength criterion is summarized. Then, the research progress associated with the multiaxial strength criterion from 2010 to 2020 is reviewed. The accuracy of the concrete strength criterion proposed during this period is analysed and compared with the collected multiaxial strength experimental data of 777 groups of concrete using a statistical method. The analysis shows that the six-parameter strength criterion for ordinary concrete proposed by Ding-Wu, the three-parameter strength criterion based on the Willam-Warnke criterion for high-performance concrete proposed by He-Song and the six-parameter strength criterion for lightweight aggregate concrete proposed by Liu-Song are in good agreement with the experimental data collected.
