A circular concrete-filled steel tube (CFST) has several advantages compared with reinforced concrete member or hollow steel tube, since the tri-axial state of compression of the concrete infill increases its strength and strain capacity. In this research investigation on the behaviour of Self Compacting Concrete Filled steel tube (CFST) is carried out. Composite Circular hallow steel tubes with infill of different grades of Self Compacting Concrete are tested for ultimate load capacity.steel tubes are compared for different lengths, thickness and grade. The Obtained results were compared with American Concrete Institute (ACI), Euro Code-4(EC-4) and modelling is carried out using FL (Fuzzy Logic) technique which is a soft tool in Matlab-R2018b. Fuzzy logic is a problem-solving control system methodology that tends itself to implementation in systems ranging from simple, small, embedded micro-controllers to large, networked, multi-channel PC and control systems. It can be implemented in hardware, software, or a combination of both. A fuzzy logic controller can be regarded as an expert system that is able to process qualitative variables and to infer crisp values out of uncertainty. Hence, fuzzy logic can be find application in many aspects of real life, where there is a lack of information, there is uncertainty.
