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.

Behavior Factor

During alternate loading cycles, as during earthquakes, the structure behavior becomes inelastic. This is particularly the case for steel structures. They show a better ability to absorb earthquake energy. This energy dissipating capacity is described by the q global behavior factor as used in the Eurocode 8. However, in other earthquake codes, it is expressed by R letter and in others only the X and V shapes bracing systems are taken into account in the seismic design. In this work, a method for determining the global q behavior factor is presented for eccentrically braced steel frames that are designed to resist seismic loads.
