distribution and the resulting stresses vary considerably with the cross-section
depth. With greater depth, higher temperature stresses occur.
Figure 10.10 10 shows the temperature distributions and the corresponding
self-equilibrating stresses in three bridges of the same depth but with the
cross-section con

gurations shown in Fig. 10.9. Fig. 10.11 shows the
distributions of temperature and self-equilibrating stresses in

sections varying in depth from 0.25 to 2.25 m (10-89 in).

Figure 10.9 Bridge cross-sections analysed by Elbadry and Ghali to study effects of section
shape and depth on temperature distribution: (a) solid slab; (b) cellular slab;
(c) box girder.
