Adhering to Regulatory Requirements in Calculation of Earthquake Resistance of the Structures of Life-Saving Buildings

Introduction. The scientific problem lies in ensuring earthquake resistance of the buildings by optimizing design solutions, selecting the computational models and developing a methodology, which takes into account the nonlinear behaviour of the load bearing structures under the action of design-earthquakes and reference-earthquakes. For adhering to regulatory requirements in calculation of earthquake resistance of the structures of life-saving buildings, the nonlinear calculations of structures’ behaviour under intense seismic actions were made.

Materials and Methods. The calculations were made by the analytical method and the finite element method using the “STARK ES” and “LIRA-SAPR” software.

Results. The comparative computation results of the estimated multi-storey building dynamic model subject to the horizontal progressive dynamic action with the use of eigenforms in a linear formulation have been obtained. In addition, the results of dynamic calculation under the main and special combination of loads and corresponding combination of internal forces performed for the estimated structures of a multi-storey building with seismic isolation constructed in Grozny have been presented.

Discussion and Conclusion. The criteria for selecting the significant and excluding the insignificant forms of natural oscillations when performing the earthquake resistance calculations of structures with certain nonlinearities have been determined. The calculation results have demonstrated achievement of the required bearing capacity of a multi-storey building in the given calculation conditions.
