A standard base plate connection is commonly adopted for column bases of low-rise steel structures. In most practical design, the column bases are likely covered by shallow concrete slab to hide the bolted base plate and level the slab. Cyclic loading tests are conducted, and the effects of thickness and shape of slab are investigated with reference to the standard base plate connection. That experiment showed that shallow embedded-type column base's strength and stiffness was better than exposed-type's. But its strength decreased at large deformation area. So we reinforce the column base with steel bars because we intend to prevent its strength from decreasing. The test show that the covering slab and steel bars contributes to both the initial stiffness, ultimate strength and strength decreasing.
