2.2.2 6-Foot Long Beams<br />
a) Beam ZC6 and Beam ZC6(2)<br />
The first 6-foot beam tested was ZC6 (Figure 2.6). I-point loading was performed on<br />
this beam. Vertical flexural cracks were the first to form. It was followed by flexuralshear<br />
crack. Ductile behavior was observed in this test. The peak load for the whole<br />
test was 19.1 kips. It was a shear-flexural failure (Figure 2.17). To eliminate the<br />
shear-flexure failure <strong>of</strong> the beam, it was decided to test another control beam ZC6(2)<br />
(Figure 2.7), and 2-point loading was performed on this beam. Typical shear failure<br />
was observed for beam ZC6(2) (Figure 2.18), with a failure load at 19.3 kips.
