Abstract: To this day, the connections of precast concrete buildings offer little or no continuity to the structure. Consequently, when compared to monolithic structures, the material is clearly not used to its full capacity. Studies on rigid connections, welded or assembled by post tension, have been carried out by a few investigators. Although structurally valid, none of the proposed connections proved able to meet the needs of the construction industry, due to stringent erection tolerances and complexity of assembly. The work presented here concerns the development of a bolted rigid connection system likely to be used on a large scale by the precast concrete construction industry. The study is separated in two parts. The first is concerned with the development and tuning of the new structural system while the second one deals with the determination of the rigidity of the proposed connection. The connection behaviour is then used to compare the amount of material used in the new system and the actual precast system. The software Visual Design was used to analyse the building structure, and the finite element software ANSYS to determine the characteristic behaviour of the new connection. The intent of the research is to establish the feasibility of the proposed model, so that future research and development efforts can be carried out in partnership with the precast industry.
