For an high-rise rcsidcntial building,  the hcight, ratio of hcight to width,the type of structure and the floor slab dcsign arc introduccd. The pcrformance of the building is complcx, and is difficult to dcsign. The dcsigning of pilc-raft,analysis of the uppcr structurc's dynamic propcrtics,  adjustrncnt of the structural stiffncss,  the dcsigning of comfortability undcr wind action ctc. arc dcscribcd. It may be rcfcrrcd by the dcsigning of the similar projcct.
