The structural design applications and mechanical properties of high-strength concrete (hsc) are briefly reviewed. Analytical designstudies of reinforced hsc bridge piers and columns subjected to static and seismic loadings are presented. Flexible and rigid foundation systems are incorporated into the analysis. The results of this study show that the use of hsc will reduce column size and stiffness. As the columns become more flexible, seismic shears and moments are reduced. Cost estimates show that the use of hsc with minimum reinforcing steel provides the most economical solution for bridge piers and columns. Economy is also achieved because smaller foundations canbe used. This paper appears in transportation research record no. 1180, bridge design and testing.
