Abstract. Results of the experimental study concerning the seismic resistance of partitions made of tongue-and-groove slabs of "KNAUF-gypsum slabs" assembled with the glued mortar mix "KNAUF-Fugen" are analyzed. Dynamic test of two series of partitions with a natural size of 2.5_3 m on the two-component vibro-platform have been conducted. For tests have been used two experimental samples of partitions: without external reinforcement and with the strengthening from two sides with the basalt lath of GRIDEX ÑÁÍÏñ produced by OOO "REKSTROM-K" installed in the plaster layer on the basis of gypsum mortar "KNAUF-Rotband". The frequency-amplitude spectrum under dynamic impacts on the samples varied within the interval from 1 to 8.4 Hz. At this, the amplitude of vibrations during the tests varied from 2 to 74.7 mm horizontally and up to 22 mm - vertically. The acceleration of the platform varied within the limits from 0.1 to 5.8 m/sec_. The results of tests show the efficiency of application of the basalt mesh for excluding the progressive collapse of partitions at earthquakes of 7-9 point intensity according to the MSK-64 scale. Recommendations on the scheme of arrangement of links connecting partitions with bearing elements of the building are made.
Key words: experiment, seismic load, frequency-amplitude spectrum of impacts, partition made of tongue-and-groove slabs, composite mesh on the basis of basalt fiber. - REFERENCES
