![]() This structure is subjected to its self-weight and finishing dead loads at each story (refer to Figure 1).Ĭonstruction stages are defined according to the actual story by story construction sequence (Refer to Figure 2). A good example where this effect should not be overlooked is in analyzing frame structures with transfer beams.Ī steel frame structure with a transfer beam in story 1 is considered. Neglecting the construction stages effect in the classical analysis will sometimes yield wrong results. Therefore, at each construction stage, the distribution of displacements and internal forces in the completed parts of the structure (due to the existing loads) is not affected by elements of upper stories that do not exist yet. ![]() However, in practice, structures are constructed in stages (story by story) and loadings such as self-weight, construction and finishing loads are present at each stage prior to structure completion. In other words, no loading of any type is applied on the structure until the entire construction process is completed. In conventional structural analysis, all loadings are applied at once on the complete final structure before studying their effects in a single step calculation. Keywords: Advance Design, Construction Stages, Transfer Beam. For this purpose, a result comparison between Advance Design construction stages and classical full model single run analysis are presented for a steel frame model with a transfer beam. ![]() This article highlights the importance of construction stages in studying frame structures with transfer beams. ![]()
