Design of Steel Structures in Seismic Conditions

The principles of designing earthquake-resistant steel frames of industrial buildings are considered. Particular attention is paid to the causes of damage to steel frames due to seismic loads impact, as well as the requirements that must be met when designing steel frames in seismically active areas. The most suitable materials that can be used to strengthen the steel frame, because of its correct operation relative to the resulting seismic loads have been studied. The analysis of loads calculated according to the normative documents of Russia and other countries of the world, and their comparison with each other are presented. An overview of possible experimental methods for determining the strength of the frame under seismic loads is given, as well as a critical assessment of the regulatory documents used, namely the formulas and coefficients used, and alternative solutions are proposed. The influence of soil on the strength parameters of the steel frame under seismic load, as well as the influence of own vibrations and forms of the structure on the pliability of the bases, were studied. Promising design solutions for steel frames in the event of earthquakes are indicated. The experience of designing earthquake-resistant structures abroad was studied and the materials of past accidents in Russia and other countries of the world were analyzed.
