CARRILLO LEON, Wilmer Julián. ESTIMATION OF THE NATURAL VIBRATION PERIODS IN TRADITIONAL HOUSING WITH CONCRETE WALLS. Cienc. Ing. Neogranad. [online]. 2009, vol.19, n.1, pp.39-54. ISSN 0124-8170.

This research is to evaluate two modeling techniques used in the practice of structural design by the vibration periods in traditional housings with concrete walls. The analytical results were compared with the results obtained by atmosphere vibration testings. In the research was taken one and two floor housing with traditional low walls in Mexico. Although there are signiflcant uncertainties to carry out analytical models, it is considered that the two analytical methodologies are suitable for estimating vibration periods of this type of structures. Just as it was expected, the results of the finite element method are closer to the experimental findings. Also, vibration periods achieved with the wide column method are higher than the experimental ones.

Palavras-chave : vibration period; concrete walls; ambient vibration test; numeric models; wide column method; finite elements.
