THE DEFORMATION AND STATIC RESEARCH OF HYDRAUMATICSYNCHRONIZING LIFTING CONSTRUCTION TECHNOLOGY

摘要

In construction of the steel roof a computer-controlled hydraumatic synchronizing lifting constructionrntechnology was adopted. Adopting this construction technology the steel roof could be assembled on the groundrnso that the safe could be ensured and the construction fee could be dropped. However, it differs from otherrnsimilar project in some points. First, the steel roof had large area , long-span and many lifting points; next, thernstructure form in lifting process differed from the design status; at last the deformation of steel roof in liftingrnprocess could not been ignored. If these characteristics could not been considered in lifting process, it maybernbrings large project accident.rnSo the deformation and static analysis were researched in lifting status to find out what are the main factors. Atrnlast the researching conclusion can be used by the similar construction.
