摘要：
This article provides an example of the calculation of eccentrically compressed reinforced concrete elements operating under dynamic loads and fire effects. Dynamic coefficient depending on temperature and strain rate, the results of experiment varies widely from 0.4 to 0.8. It is possible to reveal the influence of the dynamic effect on the reduction of the bearing capacity of the pylon and fire and columns of 40%.
