Parametric regulation of reinforced concrete structures

Introduction. The Strategy of the Development of the Construction Industry and Housing and Communal services in the Russian Federation provides for the transition to parametric regulation in construction. The article attempts to examine the essence of such a transition in terms of the design of load-bearing reinforced concrete structures from various perspectives. The article discusses the features of such a transition compared to the current principle of regulation, highlights various aspects of such a transition, and examines the possible consequences of their impact on the overall design process. The transition to parametric regulation has both advantages and disadvantages, and therefore the implementation of such regulation in the design practice requires careful and comprehensive assessment, taking into account the existing domestic experience in the design of reinforced concrete

structures.

Aim. To assess the transition to parametric regulation in the design of reinforced concrete structures.

Materials and methods. The assessment was performed based on an analysis of the provisions of the Strategy for the Development of the Construction Industry and Housing and Communal services in the Russian Federation, as well as the provisions of domestic and foreign regulatory and technical documentation.

Results. The general principle of transition to parametric regulation has been analyzed, the positive aspects of such a transition, as well as its disadvantages, have been noted.  Proposals have been formulated to eliminate the disadvantages of transition to parametric regulation in the design of load-bearing reinforced concrete structures.

Conclusions. It is necessary to take into account the development of technologies, calculation methods, approaches to design, the emergence of new materials, and to implement all of this in the practice of designing of concrete and reinforced concrete structures. At the same time, the introduction of such innovations should be based on the fundamental principles of ensuring the reliability and durability of the adopted design solutions. In order to eliminate the shortcomings, the implementation of parametric standardization in the design practice requires careful and comprehensive assessment, taking into account the existing domestic experience in the design of reinforced concrete structures. It seems to be necessary for transition to parametric standardization to prepare a system of voluntary use documents that will allow designers to solve all the problems of building structures designing.
