Steel column base connections represent a critical aspect of modern structural engineering, particularly in seismic regions where the integrity and ductility of these joints can determine overall ...

Q: The outside of the Lally columns in my under-the-house garage have rusted out at the bottom. The inside concrete looks OK, but is the outside steel layer important? A: Lally columns are made up of ...

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 compressive ...

Builders of the tallest office tower under construction at ground zero have set a 70-ton piece of steel into place — the largest column installed yet at the building. Three more columns are set to go ...
