THERMAL STRESSES AND DEFORMATIONS IN NONPRISMATIC INDETERMINATE COMPOSITE BRIDGES (ABRIDGEMENT)

A method is presented for determining thermally induced stresses and strains in composite girder bridges and structures with nonprismatic sections subjected to any temperature distribution. The paper also gives the expected stress range of a typical 4-span composite highway bridge with a concrete deck and steel stringer at two arbitrary temperatures. The assumed thermal coefficient of expansion for limestone-aggregate concrete is stated. The maximum longitudinal stresses in the slab for the 2 assumed thermal loadings were 1810 k Pa (262 1bf/sq. in.) for the constant temperature gradients and -3920 kPa (-568 1bf/sq. in.) for the linear slab and constant beam gradients. Maximum longitudinal beam stresses are also discussed.
