Simulation of the State of the Rod Elements of the Building Construction

This article focuses on the formation of the rod model based on analytical expressions describing the elements of the building frame elements and taking into account their physical condition. The rod elements are extensively used in the construction of buildings. These are the frame elements - beams and columns, which usually have constant cross-sections. To a Single analytical models have been formed for typical structural elements to greatly simplify the modeling on the first level of the hierarchy superelement systems. Also the analytical expressions relating the internal characteristics of the straight bars with boundary conditions at the nodes (the equation of state of the rod) have been made. The use of analytical models can more fully take into account the state of load-bearing frame structures when performing, for example, the analysis of the viability of the building frame. Given that the basic elements of modern frame buildings are the rods (frame), then the use of the calculations discussed in the article about an analytical model is quite rational.
