Principles of energy theory development for resistance of reinforced concrete

Abstract

Abstract. This paper presents principles of a novel approach to calculation of reinforced concrete structures by based on "calculated cross-section" method. It made possible to solve the problem of transition of a reinforced concrete crosssection from "continuous" state to the state "with a crack in a stretched zone". This solution allows creating unified methodology for calculating durability, rigidity and crack resistance in the framework of the theory of reinforced concrete resistance.

Control of stress-strain state in double-span reinforced concrete beams

“…It is characterized by the development of active seismic protection and isolation systems, the use of which allow managing within certain limits the regulation of stresses in buildings and structures during earthquakes [17][18][19].…”

“…While working on the energy theory of reinforced concrete and a new end-to-end method of reinforced concrete analysis based on energy diagram method [14][15][16], practicality of cracks generation while producing RC structures was proved both theoretically and experimentally.…”

Behavior of bearing reinforced concrete panels in the process of combined action

“…Investigation of the behavior of structures under combined action, namely power and fire, helps to give a more accurate characterization of the structural stability under extreme conditions [5][6][7]. This issue is relevant because most residential and industrial buildings are built of reinforced concrete structures [8,9]. The heterogeneity of the materials constituting the reinforced concrete, when heated, leads to different temperature deformations, disrupts the bond between cement stone, coarse and fine aggregate and reinforcement.…”
