Proposal of the stiffness design model of the column basis
conference paper
The connection between the steel column footing and the concrete foundation has a rotational rigidity significant for the overall frame analysis. This rigidity could be taken into account to predict the horizontal drift of the frame in serviceability limit state. A pi J posal of the stiffness design model compatible with stiffness prediction according to Eurocode 3. Annex J is presented in the paper. The model is based on the component method. Three patterns of the base plate internal forces distribution represent different collapse modes based on axial force - total bearing capacity ratio. The prediction model is compared to experimental observations. A parametric study of the main parameters of the model is included.
