26、 3). When partial-length creep specimens are used, only eight joints shall be considered (Joints 1, 2, 5, 6, 9, 10, 13, and 14 in Figure 6). Creep (DJntn) of a bonded cross-section shall be the average of the four creep measurements D1, D2, D3, and D4(see Figure 5).The calculations for each creep sp
