The patent is the result of many years of attempts to manufacture economical and long-lasting glass units with more than three panes. The idea of the solution is to combine two findings: a) buildings that have glass with very low thermal transmittance, do not need variable external shading, and b) multi-pane insulating glass having suncontrol external glass (reflects solar NIR), and low-absorption intermediate panes, achieve with these optical measures such a reduced temperature of the intermediate panes that there is no need to heat-treat the intermediate panes and further that the temperatures are low enough to use the known sealing systems.

COBISS.SI-ID: 22261507The building panel is structure of external and inner plate where there is intermediate insulation space between the plates. In this space there can by any kind of thermal and/or sound insulation which does preferably not form solid structure in connection with plates. The connection forms connection between plates. The connection is implemented at least along the longitudinal part of panel frame. Further the connection comprises the attached polymer based profile or stack of spacers.

COBISS.SI-ID: 169243Vibration fatigue describes the fatigue of flexible structures where the excitation forces lie in the frequency range of the natural dynamics of the excited structure. The goal of vibration fatigue is to understand the mechanics of failure and to estimate the fatigue life. Classical fatigue usually tries to estimate the fatigue life in the time domain, while vibration fatigue mostly estimates the fatigue life in the frequency domain. Initially, only the fatigue load counting methods in frequency domain have been researched; however, recent years have seen a significant progress in the field of structural dynamics based fatigue research. This contribution will present the recent status in the field of vibration fatigue. Initially the basics of the uniaxial vibration fatigue will be presented, including the typical and the recent frequency domain counting methods, e.g.: Wirsching-Light, Gao-Moan, Dirlik, Zhao-Baker, Tovo-Benasciutti, Petrucci-Zuccarello. As the uniaxial approach is very limiting the multiaxial criteria (e.g. maximum normal stress, maximum shear stress, maximum normal-and-shear stress, C-S criterion, Projection-by-Projection and the Preumont and Piéfort criterion) have gained a lot of attention in the last five years. The theoretical and experimental comparison of different approaches will be discussed. Further, a new approach, which is based on the modal decomposition, where the fatigue damage estimation is performed on the modal model will be presented. Most recent research (last 2 years) in the field of vibration fatigue is focused into non-Gaussian and non-stationary loads. Recent theoretical and experimental research will be discussed to show the importance of the non-stationarity and the non-Gaussianity.
