PROSPECTIVE AND NECESSARY DIRECTIONS OF DEVELOPMENT OF STANDARDS IN THE FIELD OF DESIGN OF STEEL STRUCTURES

Abstract

Constant theoretical and experimental research stimulate the development of design methods, which in turn causes the need to update design standards taking into account the needs and current situation of the real sector. In the domestic and world practice of designing steel structures, it is possible to identify a number of relevant areas for improving design standards that are in demand today. This article presents an analysis and justification of promising areas for improving design standards in the field of steel structures. The solution of the listed priority areas and the regulation of technical instructions in regulatory documents will improve the quality of design work, reduce the subjectivity of making design decisions, thereby increasing the reliability of solutions, in some cases, without reducing reliability, to obtain more economical and modern design solutions. Summing up, it is possible to identify a number of priority areas that cannot be bypassed when updating standards: regulation of rules related to the implementation of structural analysis; regulation of the rules for the design of steel structures based on experimental data; regulation of the rules for the design of steel structures based on numerical resistance models; regulation of the rules for the design of steel structures taking into account accidental actions; regulation of the rules for assessing the compliance of existing structures with modern requirements and further forecasting of the design life; regulation of the rules for the analysis and reliability of steel structures, including socio-economic optimization of the risks.
