Effective Stiffness Modifiers


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.

In this document, a model is analyzed by using both methods, then the model is exported to SAP2000 and the results are compared.
