EXPERIMENTAL STUDIES OF SEISMIC RESISTANCE OF TRANSLUCENT FACADE STRUCTURES.

The results of experimental studies on the assessment of seismic resistance of hinged facade translucent systems, glass windows and glass panels are presented. The tests were carried out on special stands. When assessing the seismic resistance of facade translucent systems, a twocomponent pendulum-type vibration platform was used. During dynamic tests of glass windows and glass panels, a stand was used, for the excitation of vibrations of which a system consisting of dynamic hydraulic jacks was used. During the tests, the amplitude-frequency characteristics of dynamic effects varied in the range from 1.0 to 25.0 Hz with the amplitude of vibrations of the vibration platform up to 70 mm in the horizontal direction and 12.8 mm in the vertical direction. The values of accelerations of the vibration platform and dynamic jacks at the specified amplitude-frequency characteristics varied in the range from 0.2 to 5.0 m/s2 in the horizontal direction and from 0.1 to 2.0 m/s2 in the vertical direction. The behavior of glass panels under dynamic impact is modeled. It has been established that the use of glass partitions wall made of tempered Triplex glass with a thickness of at least t = 18 mm using a strengthening film of the TROSIFOL brand makes it possible to exclude the collapse of the structure of glass panels during the destruction of glass. The analysis of the results of experimental studies on the assessment of seismic resistance and injury safety of glass panels under dynamic loads simulating seismic impacts with an intensity of 7-9 points on the MSK-64 scale is carried out. The necessity of developing special regulatory documents is indicated. [ABSTRACT FROM AUTHOR]
