Abstract (sommario):

Over-track buildings above metro depots have become common in megacities due to urban land shortages. The transmission of vibrations into the over-track buildings during routine train operations has the potential to adversely impact the occupants in terms of perceptible vibration and noise. There is a need to quantify the potential impacts before construction for planning and design purposes. Train-induced vibration measurements were carried out on a six-story over-track building at the Luogang metro depot in Guangzhou, China, which is located adjacent to the tracks. The measurements were used

Abstract (sommario):

This paper presents the problem of rail transport vibration transmission from the ground to building foundations. Field measurement results of vibration parameters on the ground near buildings and their foundations have been covered in this study. It has been shown that vibrations at the foundation of a building are much smaller than vibrations on the ground. The most intense vibrations on the foundation slab occur in the vertical direction. Comparison with other experimental data on vibration transfer from the ground to buildings structures has been made. The data obtained can be utilized in

Abstract (sommario):

The Zagreb 2020 earthquake severely damaged the historic centre of the city. Most of the damage occurred on historic masonry residential buildings, many of which are situated very close to the tram track. Although traffic-induced vibrations generally do not affect surrounding buildings, they can be harmful to buildings damaged by a previous earthquake. Vibrations could contribute to the further propagation of existing cracks. The effect of vibrations depends on many factors, one of the most important being the distance between the track and the building. The vibrations are highest at the sourc

Abstract (sommario):

This paper presents the problem of vibration transmission in building structures, which is induced by rail transport, and it discusses the effect of acoustic isolation used at the foundation. The vibration sources generate acoustic waves which are transmitted to the foundation and propagate trough the floors and slabs of the building. The transmission coefficients of the acoustic waves induced by metro trains and trams were determined in the building foundation and slabs. It was shown that mechanical resonances have a significant influence on the vibrations of the slabs. The characteristics of

Abstract (sommario):

Constructing buildings above subway tracks exploits urban-area space intensively by adopting the three-dimensional overlapping development mode, which is one of the important measures for solving the contradictions among urban population increase, land resource shortage, and environmental protection. However, the vibration generated by the frequent train operations is transmitted to the upper buildings through the track structure and ground soil, which can cause structural vibrations and radiated noise and bring physical and mental side effects to occupants within the buildings.

Abstract (sommario):

Vibrations caused by blasting works have an impact not only on buildings but also the internal environment of the buildings. If these buildings are situated in the surroundings of quarries, the citizens can perceive these vibrations negatively. By applying an appropriate millisecond timing interval, it is possible to lower the intensity of vibrations to the levels that the citizens will not perceive as negative effects inside the buildings. The limit values for this vibration intensity have not been defined to date. For the protection of the building from the vibrations, normative values of th

Abstract (sommario):

During the operation of urban subway rail transit systems, vibrations are generated that transmitted through the soil, induce vibrations in nearby buildings. The transmission of ground-borne vibrations from subway rail transit systems in a building is governed by the soil-foundation interaction, the reduction of vibration level between floors, and the amplication due to resonances of building elements. These are influenced by the type of the building, its construction materials, the foundation soil, and the frequency content of the excitation. A methodology is proposed for the determination of

Abstract (sommario):

Currently, the railway network is widely developed, many of which pass through settlements and cities; in some proximity to buildings, including high-rise buildings. The movement of trains on the track causes a certain level of vibrations that are transmitted through the ground to nearby buildings, and cause vibrations of various structures. In this regard, when designing railway tracks or constructing buildings in some proximity to railways, it is necessary to assess the possible vibration impact of rail transport on structures at the design stage and, if necessary, provide measures to protec

Thus, the CTMD can be viewed as a direct approach for controlling the modal vibration of asymmetric-plan buildings. First, the CTMD is developed from the two-degree-of-freedom modal system, which has one active and one spurious vibration frequency. It i

Abstract (sommario):

The basic concept of vibration and seismic insulation of buildings and structures based on the use of rubber seismic blocks (RSB) is considered. The concept of seismic isolation of structures is very relevant. In Japan, New Zealand, France, Greece, England, the United States and a number of other countries, it has been successfully used to protect such important structures as nuclear power plants, schools, bridges, museums, administrative and residential buildings from earthquakes. In Ukraine, the concept developed in two ways: the development of seismic isolation blocks for earthquake protect

The vibration caused by railways is an environmental constraint in the development of over-track buildings. To study the influence of environmental vibration from the high-speed railway on over-track buildings, a finite element model including track, soil, and buildings was set up. Based on the vertical vibration acceleration sampled on the rail, the equivalent line load acting on rails vertically was obtained by a simplified model. On the basis of verifying the simulation model by measurement results, the vertical vibration induced by high-speed railways in over-track buildings was studied qu

Abstract (sommario):

Base-isolation of buildings is a common solution to the problem of ground-borne vibration from urban road and rail networks. Conventional designs incorporate vibration isolation bearings between a building and its foundation, aligned in the vertical direction so as to isolate the building from vertical motion of its foundation. In some cases, in order to accommodate horizontal loads, additional side-restraint bearings aligned in the horizontal direction are required. This paper describes a theoretical investigation into the effect of side-restraint bearings on the performance of base-isolated

The most important thing in applying mass type dampers including Liquid Column Vibration Absorber (LCVA) is tuning its natural frequency to an optimum value which is a function of the natural frequency of the building and the mass ratio of damper to the building. However, exact prediction of the natural frequency of the building at design stage is very difficult especially for concrete buildings. Thus, continuous updating of the target frequency and correction of the design of the damper based on field measurement is necessary.
