This search is mainly concerned with making a comparison between three methods for analyzing
continuous concrete bridges, Priestly, Abdul-Ahad and finite elements. Three standard Design
temperature distribution, New Zealand, AASHTO and British (5400) were used to analyze the
concrete bridges in Baghdad. The analysis of two continues precast prestressed concrete bridges in
Baghdad are presented. Another comparison as made between the thermal stresses and the stress
associated with dead and live loads. Analytical results indicated that stresses and curvature values
are very sensitive to the type of temperature distribution assumed. The suggested analytical models
for the bridge can be used to be predict thermal movement and stresses due to any shape of
temperature distribution.
