Kentucky Transportation Center Research Report
When infrastructure is subjected to temperature changes, structural members that are either partially or fully restrained against motion can develop internal stresses. The phenomenon of temperature-induced internal stress development in superstructure members has prompted the American Association of State Highway and Transportation Officials (AASHTO) to include provisions for determining superstructure temperature load effects. However, little consideration has been given to explicitly quantifying the effect that thermal stresses have on foundation systems such as intermediate bridge piers. The objective of this study is to instrument a multi-span integral abutment bridge with temperature and bridge response monitoring devices, and ultimately, to make …
