Making Amendments to the Regulatory Documents Regarding High-strength Bolts Mounting Connections
The article is dealing with the issue of adjusting design standards to the changed conditions in the production of construction work. In particular, the introduction of a modified list of recommended methods of cleaning the surfaces to be joined into the design standards for high-strength bolt connections is directly considered. It is proposed to leave and to introduce only three recommended cleaning methods, one for the conditions of the manufacturer, the other for the conditions of the construction site, and the third for the repair work of the buildings and structures in use. Reducing the cleaning methods to three does not exclude the use of other cleaning methods, but given their relative technological complexity, they require the development of an additional section in the work production project, which would directly address the issues of cleaning (treating) the jointed surfaces of a particular building and structure. Similarly, proposals are presented regarding the regulation of the high-strength bolts tension based on the torque and angle of rotation.
