説明

Upper stories of a large and heavy building with an overhanging portion were lifted up. The lifted portion is about 6500 t in weight and has 156 joints connected to 4 super columns, which stand throughout the lifted portion and have 64 jacks at the top. Stress and displacements during jack loading. tiplift, curtainwall installations, the lift, connection and jack unloading were analized and temporary members were arranaed. To constrain large horizontal displacements of the lifted portion by winds and earthquakes during the lift, small jacks were set on the portion and kept touch on lead-members of the super columns.
