Abstract

The paper considers the influence of the physical and geometric nonlinearity of reinforced concrete frame structures on the formation of the stress-strain state in the phased construction of a building. The basic principles of a statically indeterminate reinforced concrete frame structure analysis with a consideration of the design scheme creation order and load application, as well as the cracking processes, are proposed. An example of the two steps of the analysis of the transversal frame of a three-storey and three-span building for administrative and production purposes in accordance with the proposed principles of the analysis is shown. The method of the analysis is based on the study of the fundamental technological scheme of the building construction with the partition of the analysis which is accomplished on the corresponding enlarged steps. With a consideration of the construction and loading order and processes of cracking in the elements, a comparison of the results of the implemented analysis in the elastic stage is done.
