Abstract:President Hotel in Dawang District of Zhaoqing is a super high-rise frame-corewall structure with many structural irregularities including the offsetting tower, skip-floor columns and off-center setback of the roof. Different programs were used to conduct elastic and elastic-plastic analysis on the structure to ensure that the whole building keeps elastic under frequent earthquake. Meanwhile, the key components were calculated under fortification and rare earthquakes, the calculation results show that a number of indicators can meet the requirements in building codes. Based on the damage condition of the structural members in the results, some effective detail strengthening measures were conducted on the key members such as bottom shear walls, frame columns, skip-floor columns, cantilever members and oblique braces with concrete filled steel pipe, to ensure the ductility of the members under seismic actions.

Keywords:super high-rise structure; offsetting tower; skip-floor column; off-center reduce
