The Republic

The actual problem for the Republic of Abkhazia — the account of seismic influences at calculation of bearing designs of buildings is investigated. The object of research is the building of the sea station in Sukhum. The spatial plate-rod model of the building frame is made by the finite element method in the software complex “LIRA — SAPR”. Based on the results of dynamic calculation the selected method for determining the seismic influences on the building frame.

The Finite Element Model

The evolution of the formation of a rotative surface formed by an arbitrary spatial curve by rolling without sliding the moving torso along the fixed torso is studied. The optimum form for creation of unique architectural appearance of a construction is received. The finite element model of the building of parametric architecture by the finite element method is developed. To confirm the correctness of the design solutions, the dynamic calculation and analysis of the obtained frequencies and eigenfrequencies were performed.

Operating Method

The article deals with the rod model for the analysis of stress-strain state of rod structures. Analytical solutions are obtained by the operating method. It is assumed that the rod elements can have variables along their axis of physicals characteristics. External loads can also vary along the axes. Calculation formulas are suitable for loads distributed according to an arbitrary law. Unlike the finite element method, defining matrices are formed after obtaining an expression, allowing to calculate the nodal forces through nodal displacements. Examples are given to demonstrate the accuracy of the obtained expressions.
