To erect a large span steel st ructure roof with the integ ral hoisting method, the st ress in some pole w ill ex ceed desig n limitat ion during the hoist ing process if the hoist ing technology is selected incorrectly. With the finite element calculation, w e have analysed the ef fect of the hoist ing point on the st ress in the steel arched f rame work in detail, and the more reasonable hoist ing technology is proposed from the view of mechanic analysis.
