Khalik N. Effect of temperature on the stress and deformation of reinforced concrete structures of buildings and structures

The proposed classification methods of strength and resource structures, buildings and structures that are under complex mechanical and thermal loads. On the basis of numerical studies carried out in Germany, Russia, Belarus, Ukraine and other states, reviewed, compiled and installed changing patterns of physical and mechanical properties of concrete and reinforcement, including current accounts, depending on the level of temperature increase. The analysis of data of many studies established laws reduce clutch armature reinforcement in concrete structures depending on the amount of temperature influence. In typical examples are concrete and concrete structures (plate, shell) the influence of elevated and high temperatures on their stress and strain.
