ABSTRACT
Contextual Introduction (Slide 3-15)
Inventory of cold formed steel profile applications with examples of flat roof applications. Actual design of trapezoidal steel sheet in flat roof configuration. Problematic situation. Main objective of GRISPE project. State of the art of standards and short description of assemblies studied during GRISPE.
Experimental works during GRISPE project (Slide 16-28)
Description of the tests campaign performed during GRISPE project with selected products and description of tests results, behaviour observations and interpretation.
Design Method (Slide 29-44)
Description of the design method for the 4 types of assemblies: single overlap with cantilevered on top, single overlap with cantilevered underneath, double overlap and continuous profile with local reinforcement. Design relation are given in function too of the loading case.
