Shallow embedded type steel column-to-footing connections are preferable for large steel structures such as steam power stations and other energy plants, because of ease of design and construction. This paper presents strength and rigidity of very shallow type steel column-to-footing connections with adequate reinforcement subjected to cyclic reversed bending moments and shearing forces. The experimental investigation was carried out in the manner where the design ultimate bending strengths of the connections assumed as the exposed type were varied parametrically. From the results of the experiment, the effect of the additional concrete cover on the overall strength and rigidity of the connections was examined by using the simplified analytical model. From the discussions, it has been made clear that the very shallow type connections whose embedding depths are about 0.6 times the column depths and covered with adequately stiffened additional concrete, can exhibit favourable strength and rigidity.
