A 1000 ft. long bridge with a steel superstructure (steel alloy A36) is subjected to seasonal temperature extremes of -40 F to 100 F. (A) How much total expansion joint space must be allowed for to keep the superstructure free from thermal stresses? (B) If the superstructure were welded and stress free at 70F, what thermal stress is developed at -40F?
