COMPOSITE SEMI-RIGID CONNECTIONS

The article describes how partial restraint connections can significantly reduce deflections, increase the frequency of vibration, and provide needed lateral stiffness. The concept of semi-rigid composite connections utilizes the additional strength and stiffness provided by the floor slab that is activated by adding shear studs and slab reinforcement in the negative moment regions adjacent to the columns. The article desribes the investigation of four different types of connections: (1) those that consist of a typical seat angle, a double angle shear connection to the web, and continuous slab reinforcement across column lines; (2) those that consist of a welded bottom plate, web angles for shear, and continuous slab reinforcement; (3) those that consist of connections similar to Type (1) except that the web angle are missing; and (4) those that consist of combining the simplest shear connection used in steel frames with the slab reinforcement. Serviceability is discussed, and performance studies are described.
