HURTADO-ALVARADO, Marcial  and  PICON-RODRIGUEZ, Ricardo. Experimental behaviour of RC interior wide beam-column joint subject seismic actions and axial load. Rev. Téc. Ing. Univ. Zulia [online]. 2009, vol.32, n.1, pp.32-42. ISSN 0254-0770.

This paper presents experimental tests that show the influence of axial load of the RC wide beam-column interior joint subjected to lateral displacements. A numerical part where the numerical results of the experimental tests is included. A damage model with slip in the wide beam-column joints is used. The numerical results and experimental tests were similar. Experimental tests with and without axial load application were performed. The axial load on the interior joint column was applied using the post-tension technique. The pinching phenomenon and energy dissipation from experimental curves were analyzed. The lateral stress increased with the compression axial load application on the joint column is reported. The energy dissipation increases when the axial load on the column of interior joint decrease. The damage levels of the simulations in the wide beam-column joints increased with low axial load on the column. The numerical results are accord with experimental tests.
