- KurzbeschreibungUse of flat plate systems has become increasingly <br>popular; however, relatively sparse experimental <br>data are available to assess the dynamic responses <br>and performance of such systems. To address these <br>gaps, shake table tests of two, one-<br>third scale, two-bay by two-story flat plate frames <br>with shear reinforcement were conducted. One of the <br>specimens consisted of a conventional reinforced <br>concrete flat plate, whereas the other specimen <br>consisted of nominally reinforced flat plate with <br>post-tensioning reinforcement. The post-tensioned <br>slab-column frames performed well, verifying that <br>this commonly used system is effective. Although <br>slab-column punching failures occurred during the <br>tests, lateral drift ratios of about 4% and <br>5% were achieved for the RC and PT <br>frames, respectively, with relatively little loss of <br>lateral load capacity. Analytical studies were <br>conducted to validate models for simulating dynamic <br>responses of the slab-column frames and to improve <br>the response predictions by implementing a limit <br>state model for punching failures. The <br>analytical models investigated were capable of <br>reproducing the experimental responses quite well.
