VIBRATIONS CAN CAUSE INCONVENIENCE IN PERSONS, QUESTIONS ABOUT STRUCTURE´S SAFETY, AND COLLAPSE RISK THAT IT IS DETERMINED BY INTENSITY OF VIBRATIONS. THE OBJECTIVE OF THIS PAPER IS EVALUATING THE BEHAVIOR OF REINFORCED CONCRETE WAFFLE SLABS DUE TO THE HUMAN RHYTHMIC ACTIVITIES. SLABS ARE MODELED BY FINITE ELEMENTS METHOD USING THE SAP2000 PROGRAM.
