The main goal in this project was to study the behavior of Concrete-Filled Double-Skin Tube (CFDST) columns subjected to fire following earthquake scenarios. For this purpose, the behavior of CFDST ...

Concrete-filled steel tubular (CFST) columns represent a mature yet evolving area of structural engineering. By encasing concrete within a steel tube, these composite members harness the ...

The Fab-Form Fast-Tube all-weather utility column form is designed for concrete applications and construction projects. This solution comes in 12- and 100-ft. rolls, as well as 8- to 16-in. diameters.

The concrete body of this machine is housed inside a 3D printed shell, which makes for an attractive skin as well as a handy mold.

How to Get a Solid, Frost-proof Footing: When you pour concrete footings, hold the cardboard concrete form tube about 12 in. up from the bottom of the footing.
