It is concluded that the general trend is that the effect is more obvious with the increase of floor numbers. The specific conclusions are as follow: 1) concrete shrinkage and creep is enlarging the axial force in the column with the increase range not exceeding 10% on the top floor, but is decreasing the axial force in the shear wall with a maximum of 27% on the top floor; 2) the impact on bending moment of beams which connect the column and shear wall is more obvious, with the increase range of bending moment of beam closely column at top story up to 30% and the appropriate decrease range of the bending of beam near wall 20%; 3) the maximum impact on beam bending moment which connects column on both sides is nearly 11%; 4) the impact on bending moment of beams which connects the column and the shear wall is focusing on the top 10 floors and the impact on lower floors can be ignored. Based on this impact pattern, corresponding suggestions are put forward on design construction measures.Keywords:concrete shrinkage and creep; effect pattern; internal force weight distribution作者簡介：林超偉，碩士，工程師，Email:wei65125036@163.com。參考文獻［1］王興法，林超偉，陳勤，等. 長富金茂大廈結(jié)構(gòu)設(shè)計及抗震性能研究［J］. 建筑結(jié)構(gòu),2011，41(5)：38-42.［2］JGJ3—2002高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京：中國建筑工業(yè)出版社,2002.［3］CEB-FIP(CMC 1990) Comite Euro-International du Beton［S］.
