Abstract
In order to study the dynamic behaviour of reinforced concrete structures affected by strain rate effect when subjected to seismic loading, the dynamic responses of the reinforced concrete shear wall and a three‐storey reinforced concrete frame were analysed with Abaqus finite element software. The Drucker‐Prager model and concrete damaged plasticity model were used, and the strain rate effect of concrete and steel was also considered. Results showed that the dynamic behaviour of concrete and steel change greatly when the strain rate effect is taken into account. For a reinforced concrete shear wall subjected to dynamic loading, there was an increase in load carrying capacity and stiffness. The results in the time history analysis of the reinforced concrete frame with the strain rate effect are different from those without the strain rate effect. Strain rate effects should be considered carefully in the seismic analysis of reinforced concrete structures.
