Abstract
Environmental vibration is an effect not always regarded as relevant in urban studies and in engineering projects. In order to quantify vibratory energy, it is common to use the peak particle velocity (PPV) parameter. PPV is obtained by the acceleration vector sum in the three orthogonal axes integrated by a measuring device, resulting in the final velocity value. However, there is no specific national legal norm to regulate environmental structural vibration, thence; international standards are in place instead. Nonetheless, these standards do not always conform to the national expectations. The objective of this study is to assess the influence of railway traffic vibration on urban environments by means of PPV measurements and to verify whether the international standards are valid for the structural conditions found in the analyzed site. In the chosen study site, measurements were performed over predetermined distances in order to evaluate for structural damage and locality inconvenience. It was verified that even though the PPVs values were below a criterion threshold, there were clear building damages. This is an indication that this subject must be further investigated for the development of parameters that better meet the Brazilian needs.
