Influence of the Vertical Earthquake Component on the Shear Vibration of Buildings on Sliding Foundations

The paper studied the vibrations of buildings on sliding foundation with dry friction under action real earthquakes at intensity 8 and 9 MSK-64 scale. It was developed a unique algorithm for calculating displacements, velocities, accelerations, shear forces resulting from simultaneous horizontal vertical components seismogram record. four-story nine-story set three earthquake records. shown that use does not always lead to significant reduction in force building floors component seismic effect has influence vibration building.
