Abstract


In reality, a building structure was built floor by floor or gradually, this is going to affect
forces in preliminary design (using Direct Loading Method). The most extreme effect in the form of
eccentricities in the column structure, there this research is giving depiction on how far eccentricities
deviation dan what factor affects column structure eccentricities as the consequence of gradual
building.This research utilizes Sequential Loading Method, that is weight loading method by trying to
imitate loading while construction execution occured with loading weight on gradual and sequential
structre model.Eccentricities on column structure will extremely decrease if axial weight was added
(column with one floor above). This research show eccentricites decrease until 26.39% or decrease as
much as 73.61% from Full Model analysis. Bekisting dismantling before structure column and floor
weight above done correctly is the main factor for a extensive eccentricites on column structure to
happen. So, bekisting dismantling should be planned very well by calculating its structure behavior.
