Title: Experimental Investigation of Column-Slab Joints
Author(s): Abid A. Shah, Joerg Dietz, Nguyen V. Tue, and Gert Koenig
Publication: Structural Journal
Appears on pages(s): 103-113
Keywords: column; joint; slab; strength
Abstract:This study focuses on the test results of column-slab joints with loaded slabs. The current experimental data combined with the previously reported studies was analyzed to find the appropriate parameters for estimating the effective column strength of an interior column joint simulating extreme loading events on the slab with service axial load on the column. The test results showed that the strength of an interior column-slab joint is highly dependent upon the restraint to the joint by the surrounding slab, the intensity of slab load, the joint aspect ratio, the ratio of slab reinforcement, and the column and slab concrete strengths. Based purely on the available test data analysis and discussion, a new design expression is also presented.
