“…Floorboard vibration amplification Table 4 shows that the vibration of the floorboard is amplified relative to the building structure column from 20 Hz to 200 Hz, while the peak frequencies of vibration are different for the floorboard and the building structure column. Amplification of floorboard vibration has also been mentioned in the literatures [35,36]. In addition, in a recently published literature [37], the first natural frequency of a concrete floorboard was calculated by modeling and numerical methods at around 30 Hz, and the subsequent vibration response indicated a maximum vibration level at the natural frequency.…”

The main negative impact of the residential buildings located on the cover structure of a Transit Oriented Development (TOD) metro depot is that residents would suffer from the train-induced annoying vibrations. Arguments accordingly arose on the possibility of evaluating indicators controversy for this application that acceleration data was more captured in the past while velocity would be more related to structure born noise. Therefore, this paper provided a relative comparison based on a measurement campaign that both velocity and acceleration sensors were installed together at the same time. The collected vibration accelerations and velocities are analyzed and discussed using the methods of transmission loss, coherence, and time and frequency domain analysis. The results indicated that even there was no differ-ence for identifying the resonance frequency of structure, but the transit mobility and human annoyance evaluation were obviously different by using velocity or accelera-tion. Attempts to establish a relationship between the two indicators using the calcu-lus method failed because they showed the largest error at the peak frequency at the same vibration level, which would have affected the evaluation results and the judgment on the choice of mitigation measures.

“…Bucinskas et al proposed a novel computational modeling approach for prediction of environmental vibration [6]. Tao et al developed a method to predict vibration transmissions from columns into girders and subsequently into the floors, and the proposed method is very effective and easy to use [7]. Zou et al developed an efficient impedance model of train-induced vibration transmission across a transfer structure into an overtrack building in a metro depot [8].…”

Train-induced structural vibration caused more and more attentions nowadays, and the present paper developed a numerical approach of train-induced structural vibration simulation with ANSYS software. The finite element model is composed by buildings, rail, sleepers, ballast and several layers of soil, and the moving load is represented by wheel-rail coupling forces, and both solid element, shell element and beam element are used in the finite element model. Acceleration time history and vibration levels of the key point on the buildings are given, and effect of different wheel-rail coupling forces and the dynamic response of the building are also numerically investigated. Comparisons of free boundary, symmetric boundary, fixed boundary and transmitting boundary conditions on the dynamic responses are also illustrated. Numerical results show that, both boundary condition and load type could affect the dynamic response of the structures near the train tracks, and validation test should be performed firstly to determine the proper boundary condition and load amplitude and frequency. The proposed numerical method provides a powerful technic tool for numerically predicting the dynamic response of train-induce structural vibration, and could also be employed to evaluate the vibration control results of different approaches.

“…Therefore, in recent years, an increase in this area of research has been observed. This problem was analyzed in particular in the field of vibrations caused by passing vehicles, i.e., cars [4][5][6] and trains [7][8][9][10][11][12][13][14][15][16][17][18][19].…”

The case study presents an assessment of the traffic-induced vibrations on humans and residential buildings, which is important for sustainable development. The analyzed residential building had several cracks in the walls. Control gypsum tapes were applied to all cracks in the building and additional elements near the road to determine the propagation of the damage. To determine the harmfulness of vibrations for humans, vibration acceleration measurements linked to road traffic inside the analyzed building were carried out. The vibration velocities inside the object were set based on the integration of the obtained accelerations. The experimental field investigation was carried out in places where humans commonly stayed (on the first floor) at the points where the vibrations are transmitted from the construction to humans. The study involved a time history analysis, a Fast Fourier Transform (FFT) analysis, and Root Mean Square (RMS) acceleration and velocity in a one-third octave bands spectrum. Based on the conducted experimental tests, it can be pointed out that the received velocity values in the tested building, caused by the passage of various vehicles, were below the permissible levels. However, it was noticed that the distance between the building and the fence had an important role in damping vibrations emitted by passing vehicles. The presented case study may be of use to other researchers who will be involved in similar cases and want to include sustainable infrastructure development.
