Resumen:

To study the dynamic behavior of typical temples of the 17th and 18th Centuries stone masonry construction in Mexico, a shaking table test program is being performed on a 1:8 scale model built with the same materials and techniques than its prototype. Results of a first stage of the research in which the model was submitted to horizontal and vertical motions of increasing intensities are presented in this paper. The test was stopped at an intensity corresponding to a base shear force of about 40% of the total weight, causing a damage that was considered as possible to be repaired. Vertical component of the motion showed to significantly affect the response and to increase the damage of the model. Damage patterns were similar to those observed in actual temples. Main features of the measured response are compared to those computed from a linear elastic, finite element model. The degree of damage and the variation in the amplification of the response are correlated to the variation of the fundamental vibration period of the model. © 2008 Taylor & Francis Group, London.
