Force Analysis of Steel Column Base Plate Base on the Interaction Principle

Abstract:

This paper analyse the force of the column base plate which suffering the axial pressure. First, the comparative analysis between the traditional model and interaction model is made. Second, for the steel frame, sole plate and concreat base as a entirety, analyse the factor which affect the stress distribution of sole plate and base top at the different working condition. Result shows that, there is a big gap on the result between the traditional model and interaction model, difference of length-wide ratio of box column section have a small affect on the stress of base top. The change of concreat strength have a big affect on the sole plate and concreat stress distribution.
