Concrete-filled steel tube (CFST) columns are increasingly used in composite construction. Under axial compression, the steel tube will sustain partial axial force and meanwhile provides the ...

As for CFST columns with multiple cavities, Wu et al. (Wu et al., 2017) conducted tests on six columns under cyclic uniaxial compressive load, scrutinizing the effects of cavity construction, ...

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 ...

This paper investigates the effect of a series of concrete mixes that contain plastic waste aggregate on the behavior of concrete-filled steel tube columns under axial load. Two groups of specimens, ...

Congratulations Professor !! Inspirational experimental work. A lot of work has been done on this topic (concrete filled tubes) in the past but the shear strength perspective wasn't explored that ...

Columns play many roles in the landscape.Dig a 2-foot- deep hole with posthole digger; it will be about half the diameter of the cardboard tube. Dig a shallow (4 to 6 inches) depression around the ...

A well-built concrete slab will have reinforcing steel rebar cast in it, or 2-feet-by-4-feet expansion joints every eight feet or so, and even so, it may still crack.
