Calculation of Earthquake Loads and Development of Constructive Solutions in the Design of Seismic Residential Buildings

The article analyzes complex approaches to calculating earthquake loads, selecting a structural system, and increasing seismic resistance in the design of residential buildings in seismically hazardous areas. The study developed a step-by-step algorithm for seismic calculation based on QMQ 2.01.03-19, QMQ 2.01.07-96, current design requirements for reinforced concrete structures, and the principles of Eurocode 8. In this case, the dynamic properties of the building, soil conditions, mass distribution by floors, structural regularity, center of rigidity and center of mass imbalance, foundation-soil interaction, and structural detailing requirements were taken as important criteria. The article evaluates the effectiveness of monolithic reinforced concrete frames, stiffening walls, diaphragms, and connecting elements for multi-story residential buildings, and proposes structural solutions that can be used at the design stage.
