The National Concrete Masonry Association published a brochure entitled "Details for Concrete Masonry Fire Walls" identifed as NCMA TEK 5-8A. You should be able to get a copy from your state association, if not, NCMA telephone number is (703) 713-1900. The brochure discusses the options available. If you think you want to go with columns each side of the wall, it Refers you to Commentary "M" of the Supplement to the National Building Code of Canada for how to design the anchors between steel and masonry to allow for failure of the steel on one side.
Your question was also answered on page 9 of Modern Steel Construction / January 1996. The writer listed two articles by NFPA and one by Factory Mutual. He said that none of the articles appeared enthusiastic about tied walls. He stated that free standing walls were generally more easily built and can be more reliable in a fire situation.
