%X This article gives the method of dynamic calculation of reinforced beam-column concrete elements for dynamic loadings varying with time. The results of experimental researches of reinforced concrete elements under dynamic loading in fire exposure conditions are presented, and dependence of the dynamic strengthening coefficient of the elements at a temperature up to T = 9000 C is obtained. The main scenarios that can arise in high-rise buildings with progressive fracturing are developed. The analytical calculation of the change in the load-carrying capacity of reinforced beam concrete column is carried out for different thermal-force actions. Numerical analysis of a multi-storey reinforced concrete frame in the Sap 2000 software complex is carried out, taking into account the change in the strength and deformation properties of load-carrying elements for different temperature actions by means of the plastic hinge function.
