... Tests o deflection of IGU components in operational conditions are described in [19] and in ulated pressure or temperature changes in [10,20,21]. In [22], Galuppi et al. experimen verified the BAM model [14] for double-glazed IGUs, in the range of line-distributed concentrated loads and also at high temperature. Studies of external load sharing in ble-and triple-glazed IGUs are described in [23,24], and tests and numerical analyse this topic, using IGUs with laminated glass, are presented in [25,26]. ...

... Moreover, the suspension system's capacity to uphold enough tyre contact with the ground results in enhanced vehicle handling, heightened steering response, and improved B Kamalakkannan Kasi kamalsrmist@gmail.com 1 Vehicle Dynamics Laboratory, Department of Automobile Engineering, SRM Institute of Science and Technology, Kattankulathur, Chennai 603203, India overall stability [7]. Ride comfort and safe vehicle handling can be achieved by reducing the vehicle's body vibration, roll, and upward motion by establishing appropriate tire-road contact [8,9]. The dampers are vital in affecting ride quality and vehicle control and impacting overall automotive safety, efficiency, and driver satisfaction. ...

... Similar tests (an IGU was placed in a structure simulating a window frame) described in [21] showed that the measured deflection and stress in the center of the panes differed from the theoretical values for simple support, which may suggest elastic support. Regarding the theoretical analysis of the problem, recently, Galuppi and Zacchei [35] published a theoretical and numerical analysis on the transfer of external load between the panes of double-glazed IGUs, assuming their support with elastic beams, depending on the coefficients describing the bending and torsional stiffness of the support beams. ...

... Chalioris et al. [24] describe the utilization and validity of a customized portable low-cost SHM system that has been implemented as a PZT-based electromechanical conductivity (EMA) method for the detection and assessment of damage in bent reinforced concrete (RC) beams. Zacchei et al. [25] collected several data through SHM as well as the building information model of the real bridge and calibrated the bridge model by FEM. Based on that condition, monitoring techniques can be used for various industrial applications, especially for structural fault detection, El-Kafrawy [26] proposed a technique actually representing a non-destructive procedure with an immense benefit for SHM. ...

... In (Weatherill and Burton 2009), it was stated that "there can be substantial disparity in the way in which seismic sources are characterized," whereas in Sheikhhosseini et al. (2021), it was stated that "there does not exist a coordinated unique approach for the development of potential seismic source models." The reasons are mainly the lack of geological and seismological information as discussed in Zacchei and Brasil (2022); Zacchei and Lyra 2022). ...

... At the same time, when studying the durability of reinforced concrete, it is important to take into account the effect of chlorides on the corrosion of steel and welds [30,31], taking into account the properties of concrete [31]. There are quite a few studies devoted to the numerical simulation of the transport and diffusion of chlorides in concrete and reinforced concrete elements under cyclic exposure [32,33]. Works on the creation of multifactorial models of the penetration of chlorides into reinforced concrete structures under various conditions are also widespread [34,35]. ...

... Some authors, including Oliva et al. [6][7][8], performed an analysis of the roughness influence in terms of dynamic amplification values in a simply supported bridge and in a three-span continuous bridge. In this regard, the results demonstrated that the dynamic response was overestimated when the differences between the left and right roughness profiles were neglected in the case of 3D models with two profile lines corresponding to the vehicle circulation lines. ...
