BEHAVIOR OF REINFORCED CONCRETE MEMBERS SUBJECTED TO DYNAMIC LOADING

Abstract

The dynamic analysis and the earthquake resistant design for R. C. structures commonly have been conducted on the basis of the assumption that characteristics under dynamic loading are equal to those under static loading. It has hardly been clarified, however, whether fundamental properties of R. C. structures under dynamic loading are equal to those under static loading. The objective of this paper is to make clear the differences between the mechanical properties of R. C. members under dynamic loading and static loading. In order to investigate the dynamic behavior of R. C. members and to clarify the effect of strain rate on the properties of R. C. members, dynamic tensile tests on steel bar were carried out, and small scale R. C. specimens were tested under dynamic loading, steady-state dynamic base motion and static cyclic loading.
