Stress-strain state of insulated glass unit in structural glazing systems
(St-Petersburg State Polytechnical University, 2020) Gerasimova,E.; Galyamichev,A.; Dogru,S.
Article presents the analysis of classical and structural ways of fastening of the glass unit subjected to uniformly distributed wind load under the various conditions: modification of the fixing step in horizontal and vertical direction, change of gas-filled gap and glass panel thicknesses. Calculation is performed in FEM-based SJ Mepla software for three most common types of glass units of the size of 1200×1200 mm, 2400×1200 mm and 3600×1200 mm. On the basis of obtained results, it is possible to conclude that modification of the fixing step in horizontal direction and glass panel thickness have a significant influence on the stress and deformation values; in contradistinction, modification in vertical direction and gas filling thickness do not noticeably impact stress-strain state of a plate. Default fixing step between two adjacent supports, which is often adopted by manufactures of IGUs without preliminary calculation for actual applied load, has to be verified in each case in terms of deformation in order to satisfy the conditions of SLS. The table of recommended values of maximum distance between supports is presented. © Gerasimova, E.,Galyamichev, A.,Dogru, S., 2020

Wind Loads on a High-Rise Building
(Springer, 2020) Lalin,V.; Galyamichev,A.; Zdanchuk,E.; Mutovkin,A.; Dogru,S.
The paper presents an analysis of the wind effect on a building with complicated geometric shape, based on a comparison of the extreme wind pressure distribution airflow research in a wind tunnel and as a result of an analytical calculation based on standards. The main differences between the analytical and actual model of wind pressure on the buildings under study are shown. So the surrounding buildings do not allow large positive pressure to arise on the facades which is well reflected in the wind-tunnel tests and not taken into account in the regulatory calculation. Wind-tunnel tests show the presence of an end zone for positive pressure on the facades, while the regulatory calculation gives out only one value of positive pressure along the height of the facade. As a result of the study, the need for assessing the wind effect through physical or numerical modeling on newly built buildings, as well as sealing development objects, when the erected object is able to make significant adjustments both to the existing aerodynamic situation on the ground and to influence the pedestrian comfort of the territory. © Springer Nature Switzerland AG 2020.
