The first cities in Brazil emerged in the early sixteenth century and, with the discovery of new territories; new cities emerged whose remaining buildings must be preserved not only for their historical value, but also for their constructive techniques. These constructions are of a time where there was no intense traffic flow, the vehicles were not heavy and did not have the capacity to reach high speeds. After the industrial revolution, with the increase in road and rail transport, the concern with vibrations arising from the flow of traffic in historical buildings gained prominence, because modern cities developed around their historical centers and the flow, weight and speed of the vehicles in these areas are becoming more intense. Traffic- induced excitation, depending on its intensity and frequency, can generate or intensify existing damages, and usually cause discomfort to users. It depends primarily on the quality of the pavements, which is quite irregular in Brazilian historical cities. To ensure the safety of our historic constructions, usually of fragile materials, the monitoring of vibrations in urban environments is fundamental. This dissertation presents the most relevant construction materials used in constructions and pavements of historic cities in Brazil and a bibliographica l review and analysis of the codes and design criteria related to the effect of traffic - induced vibrations in these constructions. In order to understand how the vibratio ns propagate in these structures, two masonry walls were built in the laboratory with different mortar thickness and different types of foundation, being these subjected to mobile and impact loads. A detailed experimental analysis shows how in each case the accelerations, speeds and displacements vary along the walls, allowing evaluating the influence of the type of load and foundation characteristics in these quantities. The German standard DIN 4150 was adopted for the sensitivit y assessment.
