In this paper columns shortening and differential shortening between column and wall in concrete frames are calculated using nonlinear staged construction analysis. Also, these effects are compared using Dirichlet series and direct integration methods considering the variations of different parameters for each frame. Two dimensional frames that are representative of frames in actual 3D structures with 15 to 45 stories are studied. Effect of creep and shrinkage on the design parameters is discussed. Results of this study can be helpful as a guide in estimating and understanding how creep and shrinkage can affect the behavior of concrete structures.
