INVESTIGATION OF THE EFFECT OF FLOOR STIFFNESS ON SEISMIC RESPONSE AND RELIABILITY
The influence of the level of rigidity of floors on seismic reaction and reliability of multi-storey buildings is investigated. The effect is given in the form of a non-stationary random process with different prevailing oscillation periods. the dynamic calculations of buildings with a height of 9,12 and 17 storeys, the values of the displacements and distortions of floors, we have evaluated the influence of rigidity of floors on the characteristics of seismic response. By the method of statistical tests to determine the levels of reliability of buildings of different heights and stiffness for given maximum level of misalignment of the floors and the predominant period of oscillations of the soil. Shows the choice of the stiffness of the floors of the building, with preset parameters of earthquakes and reliability levels.
