VIBRATION ASSESSMENT IN TRADITIONAL BUILDINGS OF THE HISTORIC CENTER OF SALVADOR
Road traffic; loud sounds; vibration; damage; Historic Center.
This work aims to measure vibrations, in terms of speed, due to vehicle traffic and loud sounds, in public and private buildings in the Historic Center of Salvador and to evaluate whether the values obtained are within the acceptable parameters for traditional buildings, according to with international regulations. The Historic Center (where most of the protected buildings are concentrated), is a passage corridor with intense daily vehicle traffic and where Carnival and São João are held. Together, the research is carried out using scientific methods, adopting a quantitative, empirical and experimental approach. It is known that vibrations can cause and, mainly, potentiate existing damages, taking the building to the risk of collapse. To obtain the results, an experimental program was carried out that included measurements of vibrations through the installation of accelerometers on floors and walls of buildings. As this is an unprecedented study, it is expected that it will contribute to the expansion of technological knowledge on the subject, and, thus, to the development of Conservation and Restoration Science and to the preservation of the vast built national heritage.
