Abstract Aspecificscientific analysis on thecombination restrictionsof the concrete andsteel roofstructureconstruction was carried out using the steeldomeinstallationabove the concrete flooras anexample.Theobliqueliftingoftwolarge mainsteel beamsfortheprojectconstructionprogram was designed. A mast was installedon the existingstructural columnssupporting thesteel beams.Twolarge mainsteelbeams wereplacedon the existingstructural columns by artificialhangingand pulling with chainconnection and obliquelifting. Andstructuralstress was analyzed andstrength checkingwas conducted during the construction. Theprogramoninstallationofsuchlarge-scale steel beamsabovetheconcrete floor may provide valuable referenceto other projects.
