Differential Axial Deformation Effect (DADE) in 3D Analysis of Buildings


This design guide discusses the Differential Axial Deformation Effect (DADE) of columns and walls due to 3D analysis of multi storey buildings. 

The methods to reduce this effect using stiffness adjustment (Area Factor) & FE Floor Analysis are explored. 
Users who find unexpected force diagram of a multi-storey building, especially bending moments in top storey beams, are recommended to read this document.
