MAIN DIRECTIONS OF MODERN DEVELOPMENT OF STEEL CONSTRUCTIONS FOR BUILDINGS AND STRUCTURES

Abstract

The development of technologies for the manufacture and design of steel structures, together 
with the development of computer technologies, makes it possible to increase productivity in the 
building industry.  
The analysis and generalization of such factors made it possible to identify the main trends and 
directions of the creation and improvement of metal structures, taking into account the automation of 
their manufacturing processes and the use of BIM technologies. The highlighted tendencies make it 
possible to show both new directions for the development of scientific research and directions for the 
development of practical methodologies for determining the regularities of the stress-strain state of 
structural systems using steel. Among the main trends, the following are highlighted: digitalization 
of the metal construction industry; automation and robotization of the manufacturing and assembling 
processes;  science  intensity  of  design  and  production  processes;  greening  production,  evaluating 
design  solutions  from  the  standpoint  of  environmental  safety;  complex  optimization  of  design 
solutions. 
 The  authors  highlight  the  next  important  tasks  and  prospects  for  the  development  of  the 
creation of effective metal structures: the creation and use of high-strength steels C960 and more, the 
improvement of automated and robotic welding processes for ultra-high-strength steels with various 
metal thicknesses; development and improvement of the theory of calculation of thin-walled and 
composite  structures,  determination  of  the  actual  resource  of  metal  structures  after  long-term 
operation; introduction into the practice of creating new structures of rational and optimal design 
approaches  with  the  requirements  of  long-term  operation  and  life  cycle,  including  progressive 
collapse, reduction in the cost of fire and anti-corrosion covers for steel structures; improvement of 
building  codes  and  rules  for  the  design  of  metal  structures;  implementation  of  leading  foreign 
standards and experience; training of modern professional engineers and technicians; development of 
experimental and theoretical studies of full-scale samples of structures on the basis of creating high-
precision information models of structural systems.
