Life-cycle analysis of buildings with R/C frames

The R/C load-carrying frameworks of multistorey buildings as arbitrary spatial rod systems, consisting of columns and crossbars, are considered in the paper. The floor slabs and wall panels can be also involved in joint work with the framework. These frameworks are a classical example of statically indeterminate composite structures. A proper analysis of a stress-strain state and setting the criteria of these systems stability require the accounting of both their physical and geometrical nonlinearity. It allows one to describe the R/C structure life-cycle more exactly and to give a real prediction of its durability.
