Abstract

The process of building or retrofitting structures is affected by the velocity of construction, not only in the cost, but also due to the potential of injury that it can produce (noise, pollution, traffic problems, etc). Thus, it is desirable a construction period as short as possible. The steel-concrete composite structures satisfy these requirements since the steel and the concrete members can be prefabricated, and only the structural assembly needs to be performed on site. Currently, however, the steel-concrete composite connections are not adapted for using prefabricated slabs, which reduces the construction time and increases the durability of the building. In this way, the development of new types of these connections is clearly necessary. Connections based on the adherence between steel and concrete surfaces consist in a especially promising solution. The current state-of-the-art of the connections is still incomplete, and more information must be added to allow the practical use of this type of connection. This internship PhD project aims to analyze and discuss the behavior of connections by adherence between steel and concrete, through the connection between prefabricated slabs and steel beams section I,by means of analytical and numerical studies, which should be developed at the University of Minho, Portugal.
