Summary Reinforced concrete structure occupies an extremely important position in the construction engineering, the dynamic performance of the earthquake action is the main basis of seismic design, and the mechanical performance of its constituent materials of concrete under the earthquake strain rate plays a decisive role on the seismic performance of reinforced concrete structures.
