ABSTRACT
In the article there are presented calculations of 17 stories cast in situ reinforce concrete frame-wall residential building without rubber-steel (further r/s) bearings and with r/s bearings, under influence of seismic forces and torsion moments. The building has three spans in one direction and four in the other. Horizontal seismic load Q and torsion moment Mkкр are identified, which have influence on the building, the results are inserted into the program packet “LIRA 9.6 R9”. As it was mentioned above, appropriate calculations were made without r/s isolators and with r/s isolators and were reinforced via “LIR-ARM”. Then, the following characteristics were compared: seismic forces, reinforcement percents, periods of vibration, displacements and vertical forces of r/s isolators.
