NUMERICAL ANALYSIS ON A REVERSIBLE CONNECTION FOR STEEL MODULAR BUILDINGS

Modular buildings are a new type of structural system composed by prefabricated modular units and assembled on site through inter-modular connections. These structures can form complete building blocks with suspended ceilings and installations, including electrical and water systems. These modular solutions can be adapted to any use like hospitals, housing schools, etc. This work focuses on the analysis of structural behavior on a reversible steel connection modelling with finite element approach. To this scope, in the paper an ideal case study is considered, characterized by steel elements. The modules are assembled by inter-module connections that allow for rapid assembly on- site, without any need of skilled workmanship reducing the welding and the use of bolts. Therefore, Midas Fea NX is used to define the contact between steel elements in detail.
