Abstract

In an increasingly urbanized areas transport vibration source are closer and closer to the receiver which is a building. At the same time residents requirements for comfort in rooms are higher. In this paper influence of transport vibrations from various types of trams on human perception was tested and analysed. Measurements were made in Cracow on 11 buildings located near tramway. Human perception were investigated according to ISO and Polish standard. Basic RMS method and additional VDV method were applied because of high crest factor of recorded signal. Results of both methods were compared.

Highlights

Buildings, especially in city centers, are subjected to dynamic influences from many dynamic sources: transport, mining activity [1] or seismic [2]
During normal daily live human body is exposed to different types of vibrations: hand-arm vibrations, whole body vibrations and vibrations transmitted through the soil to the building structure
vibration dose value method (VDV) method is recommended in situations were high value of crest factor exist

Summary

Introduction

Especially in city centers, are subjected to dynamic influences from many dynamic sources: transport, mining activity [1] or seismic [2]. During normal daily live human body is exposed to different types of vibrations: hand-arm vibrations, whole body vibrations and vibrations transmitted through the soil to the building structure. In this article tramway vibration transmitted through the soil will be considered and influence of different type of trams on human perception of vibration will be investigated. There are two evaluation methods mainly used in the subject of human exposure to vibrations in buildings: root mean square method (RMS) and vibration dose value method (VDV). ISO standard [8] defines RMS method as a basic method of assessment but notes that sometimes additional methods are required. Crest factor is defined as follows: CF a w PEAK awRMS (1)
