This study deals with the seismic behavior of waffle-flat-plate structures subjected to the two horizontal components of near-field ground motions through shake table tests. The test specimen was a scaled portion of a prototype building with irregular layout of columns designed under the Spanish seismic code located in Granada, a prone seismic area of Spain, without specific considerations about the near-field nature of the seismic action. The specimen was subjected to a sequence of tests of increasing intensity until near the collapse. Preliminary results in terms of displacements, floor acceleration, input energy and dissipated energy (damping and hysteretic) are shown. The specimen dissipated more hysteretic energy that a counterpart specimen tested under a far-field ground motion in a previous study
Ávila et al. (Mon,) studied this question.
