Analysis of vibration criteria on reinforced concrete floor due to footfalls and passing vehicles

Vibration in buildings is a disturbance caused by activities from the surrounding area. It comes both from external and internal sources. This phenomenon can affect electronic equipment such as computers, and the comfort of building occupants especially in offices and residential buildings. The purp...

This phenomenon can affect electronic equipment such as computers, and the comfort of building occupants especially in offices and residential buildings. The purpose of this study was to determine the vibration criteria of multi-storey building floor due to vibration from footfalls and passing vehicles. The first objective of this study is to determine the vibration response level on the office building due to ground vibration from vehicles and footfalls.

Laser Doppler Vibrometer was used in field measurement to obtain the vibration response from loaded passenger and footfalls. For footfalls, one people, three people and five people included vibration were measured to observe the difference in vibration response. Ansys was used to model the building based on the parameters obtained from the original structural plan. ModalV and VSATs programs in Matlab were used to obtain the floor vibration criteria due to the vibration response. The floor response caused by vibration generated by passenger bus is in VC-E range. For human footfalls, the response is in VC-C, VC-A and ISO range for the three different cases. In conclusion, the vibration response from passing vehicles and footfalls does not exceed the recommended criteria. However, there is a risk that footfalls may have an effect when more people walk on the same floor panel as shown in the result, where there is a significant increase in response due to increase number of human footfalls. 2016 Thesis NonPeerReviewed application/pdf http://eprints.uthm.edu.my/9008/1/Shurl_Yabi.compressed.pdf Yabi, Shurl (2016) Analysis of vibration criteria on reinforced concrete floor due to footfalls and passing vehicles.
