СOMPARATIVE ANALYSIS OF DOMESTIC AND FOREIGN STANDARDS FOR THE CALCULATION OF JOINTS OF WOODEN ELEMENTS OF THE NAGEL TYPE

Abstract

The article presents the chronology of the development of regulatory documentation for the calculation and design of wooden structures in the Republic of Belarus. The analysis of the methodology for calculating symmetrical double-cut joints of wooden elements on metal nagels according to the construction rules of SP 5.05.01-2021 and the norms of foreign countries that have harmonized building codes with the Eurocode 5 standard, taking into account national applications. The differences in the provisions for the calculation of compounds on metal nagels in terms of assigning the value of the partial coefficient of the properties of the compound materials are revealed. A different approach to the assignment of technological parameters in the manufacture of building structures using metal nagels is noted. A comparative calculation of the joint of the lower belt of the truss with double-sided wooden plates on bolts is performed. The calculation results were evaluated according to the construction standards of the Republic of Belarus, China, Poland, Ukraine and Lithuania. It is established that the introduction of national applications established by national standardization bodies affects the results of the calculation of the joints of wooden elements on the nagels.
