Abstract

This paper deals with the rate effects on concrete and reinforcements, especially unfavorable effects for the dynamic design of concrete or reinforced concrete structures. The rate effects on concrete are divided into two effects, the rate effect on stress-strain relations and that on fracture criteria of concrete which bringsabout occasionally the unfavorable and brittle fractures of concrete and reinforced concrete structures.

It is also described that the brittle fractures are usually caused by the rapid propagation of cracks generated in concrete under the high rate loadings, which can be said to be one of the rate effects on concrete.
