Three Dimensional Analysis Model for Exposed Column-Base and Its Application to Collaborative Structural Analysis Part1 Analysis Model

摘要

This paper presents a three-dimensional structural model of an exposed column-base, that take intoaccount bi-axial bending effect. The following formulations were made:1) The model takes into account of variation of rotational rigidity due to initial anchor bolt tensioningand axial force of column-base.2) The model adjusts the maximum bending moment capacity and rotational rigidity by changing theline of action of the compressive force line and rigidity modification coefficient.
