(b) Normal and staggered tendons
Figure 4.22 (a, b) Transverse stress at concrete overlay-beam interface of a 7.6 m, 30 ° skewed
bridge (insertions show the tendon locations).

tendons oriented normal to traffic and staggered, similar to the test bridge,
were used for this case. Insertions of both figures show the tendon locations of
their respective arrangements. It can be seen that the left figure shows better
results with less tension so the tendons, two close to the abutments and one at
the center, parallel to the skewed supports were recommended. Similar para-
metric study was done on other span length arrangements (Fu et al. 2012).
