The paper analyzes the existing construction solutions of steel frames with a box-section column and an I-beam crossbar in order to use them earthquake zones, including areas low temperatures. Such will allow structure accept seismic inertial forces, while maintaining its bearing capacity throughout entire period operation. In solve this problem, study proposes frame joints, which can be used both for building on individual floors, thereby creating “flexible story” effect. authors studied articles, books patents issued Russia, United States, Japan, China Iran, analyzed factors that reduce reliability performance characteristics joints. main factor consists welded joint, is attach crossbars columns, transverse ribs body, form box section from sheets, angles or channels. joint reduced even more under conditions zones temperatures Russia. However, units without joints require special cast parts structures, reducing their availability. regard, task developing new original meet requirements
