The main functions of Hubei Workers Cultural Palace are worker-training,exhibition and so on.The main structure adopts frame-shear wall structure.There are some irregular items such as torsion irregularity,eccentric arrangement,partial discontinuity of floor,partial through-floor column,etc.It belongs to the complex out-of-code high-rise building.The seismic performance-based design was adopted to review the main components.YJK and MIDAS Building software were used to carry out elastic calculation and elastic time-history analysis of the structure under frequent earthquakes,and dynamic elastic-plastic time-history analysis under rare earthquakes and analysis of floor slab stress under rare earthquakes.The results show that the whole structure can meet the requirements of codes and achieve the predetermined performance objectives.Seismic strengthening measures were carry out according to the analysis results.In the area of large-span prestressed floor which is easy to generate resonance,the comfort of the floor under pedestrian excitation and rhythmic motion excitation were analyzed with high damping rubber cushion as the damping material.The analysis results show that the comfort of the floor meets the requirements of codes.
