Abstract
An improved W-column provides flange tabs on the top-and-bottom outside corners of the W-column flanges, and vertical bolt-on connections to temporarily mount one column positioned by a crane on top of another by bolting the bolt-on connections to the corresponding flange tabs to properly align one W-column above another W-column. The improved W-column further allows the two vertically positioned W-columns also to be connected together by bolting the web of the upper W-column to the web of the lower W-column before permanently welding the two vertical W-columns together. Once positioned, these vertically aligned W-columns are can be permanently joined together with the Arcmatic® VertaSlag® ESW-NG welding process. In this manner all vertical W-column elements of a steel framed high rise building can be quickly erected.
