摘要

This paper describes the experimental investigation behavior of crack and modes of failure of twelve beams consisting plain and fibre reinforced. The micro cracking characteristics, modes of failure, cracking loads, crack widths were investigated thoroughly. Based on these findings we have developed an equation to calculate the first cracking load and ultimate load. It relates with area of elliptical section as well as concrete strain along the load path. From the course of investigation we have observed that in deep beams, elliptical shape concrete strain distribution was observed along the load path.
