“…The popularity of the FEM method is gradually increasing due to its important advantages [7,8]. Expensive experimental tests can be replaced with the FEM analysis [9][10][11][12][13][14][15], which is less time-consuming while the overall costs of 6 Deformed spider with T-shape arm cross-section numerical model with 300 times magnification factor. Z-axis displacement plot such analyses are much lower.…”

This paper presents an analysis of the redistribution of stresses and displacements in numerical models of various shapes of glass connectors. Two states of dynamic wind gusts were analyzed: the maximum value of suction and the maximum value of wind pressure. For the sake of simplicity, wind gusts were assumed periodically as a sinusoidal function. The model adopts a rectangular glass plate that transmits wind pressure and suction through the point fixed glass connectors. Therefore, single-arm cross connectors were not only subjected to bending stress, but also to torsion. Four different shapes of connectors were analyzed. In the first part of the numerical analysis, T-shaped and C-shaped cross-sections were adopted, and in the next part, both connectors were modified by adding fillet welds to the models. The dynamic numerical analysis was performed using the finite element method in the ADINA program.

“…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.

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.
