Abstract

The dynamic loads in some structures like tall buildings, office rooms and gym spaces must be considered in design looking the structural safety, human comfort and material fatigue. A satisfactory structure is only obtained under these three aspects. The technical standards present distinct limit values to evaluate the human comfort. This research aims to present compiled rules about this problem. Beyond it, the state of art of fatigue limits and structural safety will be presented. The research will take national and international standards. In addition, a theoretical analysis will be carried out utilizing dynamic numerical Finite Element models representing the human action to obtain the vibration loads in distinct structures.
