Abstract

Exposed column bases employed in middle-rise steel structures can be designed and analyzed using simplified models of restoring force characteristics. The models are described with maximum bending strength and elastic rotational stiffness of the exposed column base, but without additional bending resistant capability of column axial force. This paper describes response analyses of structures with column bases of full and simplified models and the following conclusions are obtained.

The response results of the simplified models are in good agreements with those of the full models. The worst results are overestimated by 30%. Thus, simplified models can be used for rational design of steel structures.
