Embedded steel column bases I. Experiments and numerical simulation

摘要

Testing and numerical modelling of embedded steel column bases are discussed in this paper. The behaviour of two different types of experimental specimen has been analysed. The specimens were specifically designed so that the bond and punching resistances of the steel column base could be quantified. Numerical modelling by the finite element method (FEM) has been conducted to investigate the stress distributions in column bases. The numerical results have been calibrated against the test results. The testing and numerical modelling described provide a basis for establishing a design model that will be introduced in Part II of this paper.
