Abstract: Tower l#of Nanjing Walsin City adopted a structural system consisting of steel frame-comcrete core tubes structure. The characteristics of structure system, overall elastic analysis under frequent eatthquake and elasto-plastic analysis under moderate and rare earthquake were discussed systenucally. Some key design issues such as bearing capacity check of mega columns and outrigger bracing, local slab stress analysis were discussed.
Keywords: steel frame-comcrete core tube structure; outrigger; seismic design
