Numerical Investigations on Flexural Behavior of Concrete-Filled Square Steel Tubes with Embedded Steel Angles and Spiral Stirrups
To improve the mechanical performance of large-size concrete-filled steel tubes without increasing the steel consumption, this study conducted a numerical analysis of the flexural behavior of concrete-filled square steel tubes with embedded steel angles and spiral stirrups (CFSST-SASS). A finite element (FE) model was...
