The main objective of this paper was to find a relation between the velocity propagation of seismic wave and the density of the historical masonry. To obtain this information, a testing program was performed to measure the velocity of the waves in samples of a laboratory of different types of masonry and in situ from structural elements of a scale model church. According to the velocities measured and Gardner´s relation, the density of the masonry was calculated. Also, a regression model to estimate the density was obtained from the measured velocity waves. Two analyses were conducted to obtain an adequate approximation of the density of the masonry. The first was a comparison between the density measured and the density calculated using Gardner´s relation. The second was a comparison of the density measured and the density calculated using the proposed model.

本文的主要目的是找出地震波的速度传播与历史砖石密度之间的关系。为了获得这些信息，我们执行了一项测试程序，以测量不同类型砖石实验室样本中的波速，并在比例模型教堂的结构元件中原位测量波速。根据测得的速度和加德纳的关系，计算出砌体的密度。此外，从测得的速度波中获得了用于估计密度的回归模型。进行了两次分析以获得砖石密度的适当近似值。第一个是测量的密度与使用 Gardner 关系计算的密度之间的比较。
