As you may remember from the CE 533/CE
534 Mechanics of Materials class, the tensile
strength of steel is measured by pulling the
steel bar as shown below (Fig. 1) and
recording the stress at different loading
stages. As discussed in Lesson 2-Material
Properties. for the concrete, however, the
tensile strength is measured using either a
flexural test (Fig. 2) or a split cylinder test
(Fig. 3). Why the tensile strength of concrete
is not tested similar to that for the steel?
