    Abstract. The stress-strain state of the braced frame at the installation stage is considered. During installation, the floors do not form hard disks, so horizontal forces are distributed between the vertical frames of the frame differently from the operation stage. Using the example of a symmetrical three-span building with a braced frame, the compliance of floors was determined and the patterns of redistribution of forces between load-bearing structures were established. An analysis of previously performed experimental data aimed at studying the operation of floors in the horizontal plane during the installation stage was carried out. The feasibility of using a discrete model of the floor disc when calculating is determined, in which it is necessary to take into account: the nature of the operation of the floor discs in terms of the distribution of horizontal forces between the connections and columns; the influence of embedment and the size of prefabricated floor discs on their performance in their plane; rigidity characteristics of horizontal elements simulating yielding disks of floors in the longitudinal and transverse directions in the design scheme.
