Assessment of the residual load-bearing capacity of reinforced concrete structures in service based on their physico-mechanical properties

ანოტაცია

This section discusses the service life of reinforced concrete structures according to design data until their reliability decreases to the permissible limits (see point “Б” in Figure 1.1). In this case, the actual climatic conditions of the location of the structure and the expected static-dynamic loads are taken into consideration. At this stage, the residual resource of the bearing capacity of the beams and slabs is predicted based on the first limit state calculation, strength and bearing capacity. The criteria and requirements of construction norms and rules [1] are utilized in the calculation, and the change in the characteristics of concrete and vivacity over time is likewise envisaged . The design loads are: permanent and temporary loads regarding HK, strength and durability being considered.
