Abstract:Use of flat plate floor systems consisting of a conventional or post-tensioned reinforced concrete slab-column system incorporating shear reinforcement within the slab-column connection region has become increasingly popular as lateral-force resisting systems in intermediate seismic zones and gravity systems in high seismic zones. Relatively sparse experimental data, however, are available to assess the dynamic responses of such systems, particularly for post-tensioned systems. To address these gaps, shaketable tests of a conventional reinforced-concrete slab-column frame (RC specimen) and a post-tensioned slab-column frame (PT specimen) were conducted. An overview of the test program and the findings is presented. Lateral drift ratios of approximately 3 and 4% were achieved during testing for the RC and PT system frames, respectively, with relatively little loss of lateral load capacity. Also, although slab-column punching failures occurred for both specimens, the degree of damage observed was less extensive than damage observed for prior quasi-static tests of specimens without shear reinforcement.
