Dynamics of a 16-storey building with a core of rigidity in a local earthquake

The behavior of a 16-storey residential building with a stiffness core during the earthquake of March 26, 2018 is analyzed. The building is located 100 meters from the tectonic fault. The absence of resonance phenomena of the building during a local earthquake was established. On the distribution of accelerations in the horizontal plane, the effect of “eight” was found. An increased value of acceleration in the vertical direction at the level of the technical floor was revealed. This could be due to the presence of a tectonic fault near the building. The energy characteristics of the building and the impact are determined, the Arias integral and the cumulative absolute velocity are calculated. At the basement level, the period of the spectrum maximum is of the order of 0.1 sec. It is established that the building oscillates in the sum of the vibration modes
