Abstract: Concrete-filled steel tube (CFST) stub columns made of various steel thicknesses and concrete types subjected to combined thermomechanical load were investigated using the finite element (FE) program, and optimization of ...

Abstract: The study focuses on the structural behavior of concrete-filled steel tubular (CFST) stub columns with conventional cement concrete and nano-silica blended (doses of 4%, 6%, 8%, and 10% nano-silica by weight) concrete core ...
