Special Issue Information

Dear Colleagues,

Ensuring the safety of designed, erected, and operated load-bearing and enclosing building structures is the most important task of engineering, science, and practice of design and operation. An important aspect of this is the development of design and optimization methods. The goals of such optimization can be not only material consumption or costs but also the risks of accidents. The relevance of preventing risks of material and socio-economic losses is the main priority, and new modern scientific research and practice will allow us to advance in its solution. The most important factors here are the force and environmental impacts on structures, such as corrosion, high-temperature heating, mechanical shocks, seismic activity, etc. The main purpose of the Special Issue is to provide a platform for discussion of the main problems related to the mechanical, fire, and environmental safety of load-bearing and enclosing structures of buildings and assessment of their technical condition. In these conditions, it is important to consider the stages of the structure's life cycle, optimal design and calculation algorithms development to ensure sustainable evolution, and the required level of comfort of the environment of buildings.

Actual load identification is a most important task solved in the course of (1) engineering inspections of steel structures, (2) the design of systems rising or restoring the bearing capacity of damaged structural frames, and (3) structural health monitoring. Actual load values are used to determine the stress–strain state (SSS) of a structure and accomplish various engineering objectives. Load identification can involve some uncertainty and require soft computing techniques. Towards this end, the article presents an integrated method combining basic provisions of structural mechanics, machine learning, and artificial neural networks. This method involves decomposing structures into primitives, using machine learning data to make projections, and assembling structures to make final projections for steel frame structures subjected to elastic strain. Final projections serve to identify parameters of point forces and loads distributed along the length of rods. The process of identification means checking the difference between (1) weight coefficient matrices applied to unit loads and (2) actual loads standardized using maximum load values. Cases of neural network training and parameters identification are provided for simple beams. The aim of this research is to enhance the reliability and durability of steel structures by predicting consequences of unfavorable load, including emergency impacts. The novelty of this study lies in the co-use of artificial intelligence elements and structural mechanics methods to predict load parameters using actual displacement curves of structures. This novel approach will enable engineering inspection teams to predict unfavorable load peaks, prevent emergency situations, and identify actual causes of emergencies triggered by excessive loading.
