Collaborating floors with trapezoidal sheet metal

The paper discusses the peculiarities of software automatic calculation of corrugated sheets for collaborating slabs called "ColdFormEc4."

Its application is illustrated with reference to a real case of an attic designed also under standard fire conditions. The criteria for verification of longitudinal shear strength using both the "m-k" and "partial interaction" methods are clearly explained.

The "Industry" version of software allows automatic processing of load tables for both the construction and consolidated phases.
