Verification of shear strengths' provisions of existing codes for self-consolidating concrete

Using self-consolidating concrete has been the subject of many studies for years. A comprehensive literature review on shear strength of self-consolidating concrete is presented. In addition, databases are created for shear strength of self-consolidating concrete in order to lead to changes or accep...

A comprehensive literature review on shear strength of self-consolidating concrete is presented. In addition, databases are created for shear strength of self-consolidating concrete in order to lead to changes or acceptance in design codes and standards’ provisions. These data were compared with the American (ACI 318-14), European(EC 2-05), Australian(AS 3600-09), and Japanese(JSCE-05) standards provisions. Results of this study show that ACI 318-14, EC 2-05, AS 3600-09, and JSCE-05 provisions are conservative for 88, 78, 95, and 100 % of shear strength data of self-consolidating concrete. Furthermore, results of shear strength of self-consolidating concrete experiments have been compared with fracture mechanics models suggested by previous researchers. The fracture mechanics models are conservative from 40 to 85% for shear strength data of self-consolidating concrete. In addition, results also compared with conventional concrete shear strength database. Statistical data analysis (nonlinear regression) was performed on shear strength data of conventional concrete to draw best fit and 95% confidence interval of data. Comparison of shear strength data of self-consolidating concrete with conventional concrete shear strength database showed that only 15% of self-consolidating concrete data are out of 95% of confidence interval data of conventional concrete shear strength data.mahdi arezoumandiMohammad Sadegh Mohaghegh Zadeh Davani AslSeyed Omid Mobarghashaghayegh afsharIranian Society of Structrual Engineering (ISSE)articleshear strengthself-consolidating concreteconventional concretefracture mechanicsstatiscal analysisBridge engineeringTG1-470Building constructionTH1-9745FAJournal of Structural and Construction Engineering, Vol 7, Iss شماره ویژه 4, Pp 172-183 (2021)
