Construction sequence analysis is important for the structural design of tall buildings. Construction analysis of a skybridge connected complex steel frame core-wall tall building is studied in this paper. The influences of shrinkage and cree Pof reinforced concrete core-wall are discussed. Some useful conclusions are obtained and can provide reasonable references for real construction.
