ABSTRACT
The article deals with the performance of a two-storey, rigid-joined double frame exposed to different operational conditions. The performance calculation made use of LORA-SAPR software, taking into account the geometrical and physical nonlinearity. Changes were analyzed in distribution of forces in the elements of the double frame during exposure to single freezing and alternate freezing and thawing. Evidence is presented of the effect the single freezing and the alternate freezing and thawing have on the distribution of forces in a statically redundant frame, causing its elements to displace.
