Prospects for improving methods for calculating building structures taking into account the level of reliability
Incoming article date: 27.09.2023Methods of calculation and design of building structures are considered that make it possible to provide trouble-free operation on time during the service life, and hence the level of reliability. According to the reliability indicator, the following scheme for standardizing the reliability of designed building structures is linked to the assessment of quality indicators of constructed structures. Indicators of design quality that are not related to strength, guaranteed with a given probability of failure-free operation, are introduced: geometric dimensions, modular deformation and elasticity, taking into account the properties of variability and technology. The appropriate safety factors are determined, ensuring mandatory protection of failure-free operation. A scheme for calculating design structures with the required level of reliability during the design, construction and operation of structures is being developed.
