Using [([e.sub.i]).sub.D], which resulted in nine points, by which a symmetric curve is produced and the tendon profile is displayed in Figure 7 by the point line, one can see that the simple linear profile in Figures 1(a) and 5 and the optimal profile in Figure 7 are very close, and in fact the parabolic and linear shape tendons can be ideal ones, if we use the expressions in (21)-(23) in . Tendons exhibit a wide range of mechanical properties matched to their functions and, as a result, have been of interest to researchers for many decades. Related searches for this page Most tendon paths are parabolic and the distance from the soffit forms to the center of gravity (CG) of the path can be calculated as shown below: Calculation of points along a parabo. Precast beams with straight, fully bonded tendons are very convenient for detailing and manufacture. The double tee was loaded to service level, 85%, ultimate, 110% and failure.
