ENVIRONMENTALLY INDUCED BRIDGE STRESSES
Although expansive-contractive movements caused by seasonal temperature changes are generally provided for by the installation of expansion devices in the bridge deck and by supporting the superstructure on conventional bearings, daily temperature fluctuations can produce significant induced stresses. A build up of grime, grit, and corrosion in these devices cause additional induced stress. As a first step of developing better solutions, it was the objective of this study to: develop an analytical method for finding induced stresses in an interior girder of a composite-girder bridge, and evaluate the magnitude of stresses induced by exposures of air temperature extremes in a typical axially unrestrained interior girder of a four span highway bridge in mid-Missouri.
