Shear characteristics and design for high strength self consolidating concrete
In conjunction with the traditional methods, artificial intelligent based modeling methods have been applied to simulate the non-linear and complex behavior of concrete in the recent years.Twenty one laboratory experimental investigations on the mechanical properties of LWSCC; published in recent 12 years have been analyzed in this study.The intersection between beams and columns in RC frames become even more congested after consideration of earthquake requirements, and placement of concrete becomes problematic in such areas.At the same time, in many of the high-rise structures, normal strength concrete does not meet the capacity requirements; this requires the usage of high-strength concrete.SCC flows into a uniform level under its own weight and fills in all recesses and corners of the formwork even in highly congested reinforcement areas.
Analytically proposed model in ANFIS is verified by multi factor linear regression analysis.
The two longitudinal reinforcing steel ratios used were 1% and 2%.
The performance of SCC/NC beams was evaluated based on the results of crack pattern, crack widths, loads at the first flexure/diagonal cracking, ultimate shear resistance, and failure modes.

Self-compacting concrete (SCC) was first developed in Japan about two decades ago.
