DEVELOPMENT OF DESIGN TECHNIQUES FOR HIGH RISE STEELWORKS
The backgrounds to solving problems in calculation, verification and design for high rise steelworks are discussed in the paper. The analysis of responsibility levels of structural elements and the limit state classification have been done. The schemes of failure sequence have been developed for lattice and shell cylindrical structures. The advice for specification of ways in the high rise steelworks investigations accounting for changes in structural parameters and maintenance are given. Classification of high rise structures depending on load carrying type structures and types of equipment is given. Matching of load carrying structures functions is the main factor of high rise structures functioning. The paper deals with the classification of limiting states. It is also established that the limiting state of the first group for the equipment is the limiting state of the second group for the structure as a whole. The analysis of responsibility categories of structures and structure components shows that ranging of components and structures for analysis efficiency increase is possible.
