摘　　要：结合一大型冶金厂房鉴定项目,介绍"虚拟柱"法在钢筋混凝土抽柱排架结构计算中的应用,对钢屋架如何等代成实腹钢梁和"虚拟柱"方法中虚拟柱截面的确定给出具体方法,并分析了排架抽柱后内力和位移变化规律及"虚拟柱"刚度对排架内力和位移的影响。It was presented the use of ＂virtual column method＂ to the calculation of RC bent frames with columns removed according to the apprasial of a large metallurgical mill building; it was also analyzed the changes in＇ the internal forces and displacement, as well as the effect of ＂virtual column＂ stiffness on the internal forces and displacement of bent frames, using specific methods for determining virtual column sections in ＂virtual column method＂ and the one of how to equate a steel roof truss to a solid web beam.

关 键 词：抽柱 排架结构 虚拟柱
