Building reliability specification by deformation based on aesthetic and psychological requirements
The structural analysis is currently based on the limit state method. Meeting the strength, rigidity, crack resistance requirements ensures the required structural reliability. But the limit state method does not allow to determine the numerical value of reliability. This can be done only by applying probabilistic methods that are greatly developed in the late 20th century. Their practical use is hindered by a number of factors, among which is the lack of reasonable values of the reliability specification. The reliability specification of structures is determined by their normal operation including deformation and vibrations causing certain difficulties. Structural failures in this case have both economic and social consequences. There are very few works considering this problem. This is most likely due to the fact that the calculation of suitability for normal operation plays a secondary role. Violation of serviceability conditions does not lead to large economic, environmental and social consequences. But it is still necessary to consider the reliability specification in this area. This article determines the reliability specification by structure deformations based on aesthetic and psychological requirements. The proposed method for determining the reliability specification is based on deflection, which, in turn, depend on the effective load and structural rigidity.
