Abstract

This study is to investigate the strain softening behaviors of concrete material in compression under rapid loadings. The length of specimen, the constraint of both ends and the loading-rate are chosen as test parameters. From tests results, the effects of these parameters on the pre-peak behaviors, the stress softening behaviors and the strain localization are examined. To measure precisely the strain in the softening region after the maximum stress, the strain measuring rod, called SMR, is proposed in this study. 1 Introduction There are a lot of problems to be solved the behaviors and failure mechanism of concrete structures subjected to impact loads. Thus it is important to investigate quantitatively th
