Methods of increasing the seismic resistance of metal structures

The purpose of the study was to investigate methods to increase the seismic resistance of steel structures to improve their seismic resistance. The research applied dynamic and seismic analysis methods and a comparative approach to evaluate the performance of materials and systems under seismic loads. Various methods of increasing the seismic resistance of metal structures were analysed, including the use of high-strength materials, reinforcement of joints, the introduction of elastic damping elements, and optimisation of design solutions. It was found that the use of modern high-strength steels and alloys significantly increases the resistance of structures to seismic influences, due to their improved plasticity and ability to deform without fracture. Reinforcement of welded and bolted joints helps to increase the overall rigidity and strength of the structure, especially in areas subject to maximum loads. The introduction of damping elements, such as rubber-metal cushions, helps to effectively reduce vibrational oscillations, thereby reducing the load on the structure during earthquakes. It was also confirmed that the use of reinforcing frames and reinforcement of the foundation by means of pile structures significantly increases the seismic resistance of buildings and structures. In addition, it was found that the use of earthquake-resistant design technologies, such as load distribution and the use of additional structural elements, significantly increases the stability of metal structures in conditions of strong seismic impacts. The study showed that careful compliance with seismic norms and standards in the design process is a key factor in ensuring the reliability and safety of construction facilities in earthquake-prone regions. As a result of the study, it was concluded that an integrated approach to the design of metal structures is necessary, considering the seismic activity of the region, which will ensure their long-term operation in conditions of seismic risks
