About control of durability of metal of steel designs
Incoming article date: 28.10.2015The questions connected with an assessment of mechanical characteristics of steel elements of designs of tribunes of Torpedo stadium in Taganrog are considered. The analysis of the strength characteristics of metal of columns received by a nondestructive method, beams, the top and bottom belts of farms and раскосов is provided. Results of processing of values of mechanical characteristics on compliance most are shown to the general law of distribution of Veybull. For values of a limit of fluidity and strength scale and form parameters, and also shift which defines critical bottom possible value of the mechanical characteristic of theoretical distribution are received. The analysis of accessory of metal of the surveyed elements to the corresponding class of durability of construction steel with the conclusion that all metal of the surveyed elements has a class durabilities not lower than C 255 that meets requirements imposed by the project to durability of metal is given.
