The paper presents a numerical analysis of mechanical wave propagation in the spatial structure of a steel grid with a rubber filling. Steel was adopted as an isotropic linear material while rubber was modeled as a Zahorski incompressible material. A properly prepared structure can reduce the dynamic effects resulting from mechanical wave propagation. Results obtained from the numerical analysis allow us to assess the impact of the material used with the dynamic interactions in the analyzed grid with a rubber filling. The results of the numerical analysis were presented graphically. Wave phenomena have been modeled using ADINA software.

“…These properties are influenced by the used materials and the interconnections between the elements of the facade system, including the anchoring method and the type of material in which the system is installed. The material of the structural layer with proper strength and insulation properties minimizes the effect of the acoustic bridge [18]. Also, the thermal pad under the mounting anchor, in addition to reducing the point thermal bridge, limits the effect of the sound bridge.…”

Designers more and more often choose facade systems with ventilated layers for external walls, especially in the case of new buildings. They are also used to modernize existing buildings. Mechanical connectors are a characteristic element of these constructions. Often, they are ignored in calculating the heat balance of rooms and the entire building. Because they pierce the thermal insulation layer they cause point thermal bridges. The influence of thermal point bridges, usually made of aluminum, i.e. a material with very high thermal conductivity, for heat transfer turns out to be significant. Such thermal bridges significantly increase heat losses through building partitions. This situation increases the heat demand in the rooms to compensate for the heat loss. The article presents the results of the analysis of the impact of mechanical fasteners in ventilated facade systems on heat transfer in the building envelope. The influence of various materials and constructional solutions on the thermal conditions in these walls was investigated.

“…The main advantage of numerical studies is the possibility of performing the analysis lowering the costs and reducing the time necessary for preparing the real specimens and carry out experimental tests. Numerical studies regarding to reduction of mechanical wave energy transfer in hollow wall blocks, in which rubber was injected/inserted in the hollows may be found in [14][15][16]. Presented in papers results show that the energy in the form of Misses-Hencky Stress (MHS) at the same point located on the opposite block surface in regard to the point of applied exciting force may be significantly reduced via rubber injects/inserts.…”

In this paper, the use of recycled rubber in the form of inserts/fillings or overlays on Ackerman ceiling blocks to partially dampen the propagation of mechanical waves from vibrating machines/devices or accidental shocks from the people movement is discussed. The numerical study is carried out with the use of ADINA software based on Finite Element Method (FEM). The energy transferred via the forced wave is observed in the form of stress plots at given time steps. Four different Ackerman blocks are chosen, which differs in height dimension and shape. In the analysis the complexity of each block supporting is simplified and each block is treated as simply supported on its external edges. The dynamic load is applied to the blocks top surface towards the bottom. For each Ackerman block the analysis is performed twice. The first sequence deals with the Ackerman block itself – without rubber filling, and the second one with insert/filling, what gives the possibility to compare the results of transferred energy. On the basis of presented in paper results, one observes that the rubber filling gives a slight to significant reduction of mechanical wave energy transfer, depending on the block configuration.
