In the present paper an innovative solution for a structurally continuous beam- column joint in prefabricated structure is described. It is rapidly executed and very safe and has been widely used in different constructions for research centers, universities and others. This type of connection is one of the distinguished features in the Multipurpose Construction System for Cuba (SMAC System). Its behavior is based on the wedge effect and friction action developed between two inclined planes in both elements being connected. Full scale tests are described herein and the results obtained proved the efficiency. Transmission of vertical loads as well as bending moments through the joint are guaranteed. This is particularly important in frame structures since horizontal loads due to wind are very large in Cuba because of hurricanes.
