Influence of vibration generated by railway traffic in urban areas
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 integr...

Environment. Urbanism. Vibração. Ambiente. Urbanismo. 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. A vibração ambiental é um efeito que nem sempre é considerado nas análises urbanas e nos projetos de engenharia em geral. Para quantificação da energia vibratória é utilizado o pico de velocidade da partícula (PVP). A PVP é obtida pela da somatória do vetor aceleração nos três eixos ortogonais que é integrado pelo medidor resultando na velocidade. No Brasil não há uma normalização específica para avaliar a vibração ambiental, sendo utilizados padrões internacionais, que nem sempre se adaptam a realidade nacional. O objetivo deste trabalho é avaliar a influência da vibração gerada pelo tráfego ferroviário no meio urbano por meio de medições da PVP e verificar se os critérios internacionais são válidos para as condições construtivas no Brasil. No local selecionado foram realizadas medidas á várias distâncias sendo avaliados os critérios de incomodidade e danos estruturais. Verificou-se que mesmo com PVPs abaixo dos critérios, há claros danos nas edificações o que indica que este assunto deve ser aprofundado para se criar parâmetros que atendam a realidade brasileira.

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. |
