Effet des murs de remplissage en maçonnerie sur la période de vibration des portiques

This paper examines the influence of masonry infill panels on the natural period of vibration of multi-storey frames in relation to seismic load resistance. Simple analytical expressions are presented to evaluate the natural period of these types of structures with varying number of bays and stories. Results obtained with the proposed formulae were found to correlate well with numerical values obtained from a dynamic analysis program. Key words: masonry infills, seismic behaviour, natural periods, frame structures.
