Abstract: The plane of a high-rise hotel office building presents an obvious “Z-shape”, there are irregular items such ascombined planes, torsional irregularities and jump-storey inclined columns, and the buildings are connected to the podiumthrough large-span steel corridors. Combined with the main features of the project, the main points of structural design wereintroduced in detail, and corresponding seismic strengthening measures were formulated for key components such as floorslabs in the slender waist area, vertical components, and jump-storey inclined columns. The seismic performance of thestructure was verified through the overall analysis and calculation under the action of earthquake, and the weak parts werestrengthened based on the analysis results. The analysis results show that the structure has good stiffness, bearing capacityand deformation energy dissipation capacity, which meets the requirements of specification and seismic conceptual design.
