Abstract

For rational and accurate analysis of concrete structures, it is often desirable to include the post-cracking resistance of concrete. In the present investigation a method was developed to obtain reliable load-deformation behavior in tension, including the post-peak softening response. To characterize the softening response, strains at various locations on the specimens, elongations for various gage lengths, and optical measurements of crack widths were made. Seven different mix proportions were used to obtain information on the influence of aggregate size, water-cement ratio, and volume content of aggregates. An analytical expression has been developed to describe the entire tensile response of concrete.
