Intumescent coating is able to provide effective fire protection with both practicality and aesthetics. In this study, expansion performance thermal physical property experiments are firstly carried out obtain the basic parameters at different temperatures. Then, response model of concrete-filled steel tubular (CFST) structure under intumescent in a established. Finally, based on experimental d...

Concrete-filled steel tube (CFST) columns are used in tall buildings and bridges, they provide more rigidity higher bearing capacity, but buckling affects their behavior. There is an exceptional need to study the behavior of these under various conditions. The numerical method beneficial supplementing experimental works explore effects parameters because limitations cost, apparatus, time progra...

The behavior of two series corroded thin-walled concrete-filled steel tubes (CFSTs) was investigated in this paper. One series, called the CT consists fourteen CFST specimens by NaCl solution, while other, AT six test pieces atmosphere. Outer surfaces were scanned using a 3D scanner machine, and complete surface profile each specimen obtained for corrosion evaluation different methods study. En...
