In ProtaStructure, effective stiffness modifiers of the slabs could be adjusted for different analysis methods. One of the methods is using the “Finite Elements Floor Analysis” which considers the vertical load cases only independent of the building. The other method is “Finite Element Analysis” by using slabs in global building model for all load combinations.

Many structures will undergo a natural sway under purely vertical (gravity) loads. These sways can sometimes introduce significant changes to the expected moment diagrams in beams.
The axial force & moment of the columns and walls can also be significantly changed due to sway.
In such cases, it is important to ensure that checks are made for combinations where notional load cases are applied in sympathy with the natural sway of the structure.
