1. Introduction
Concrete-filled steel tubular (CFST) structures is a type of the composite steel-concrete structures used presently in civil engineering and consists of steel tube and concrete core inside it. The steel tube acts as a permanent formwork and can be of various cross-sections: circular, rectangular, square and multi-side.
According to the form of concrete core, CFST members can be divided into 2 types: with solid and hollow concrete core. Elements with solid core are formed by placing plain concrete into the steel tube with compaction of it by vibrating. The hollow CFST is produced by spinning method. The point of production by spinning is ...
