【 摘 要 】

The article raises the topic of accounting for the history of erection and loading of prefabricated reinforced concrete frames of frame buildings, which are being built everywhere with the allowed violation of the technological sequence of mounting crossbars and slabs. Internal forces in the elements of the frame are determined taking into account the above factors, a comparison with the results of the classical calculation is made. The most vulnerable elements of frames, especially designed for a small temporary load, are identified. An example from modern construction is considered, when the design of the crossbars during the erection of a building was significantly different from the one, set in the usual design calculation, which led to significant changes in the magnitude of internal forces in the columns and bolts compared with the classical calculation.
