THE RELATIONSHIP OF ENVIRONMENTAL PARAMETERS TO DISPLACEMENT RESPONSES OF HIGHWAY BRIDGES (SUPPLEMENT II)

The report contains an in-depth presentation and analysis of thermal and displacement data taken from two typical highway bridges in New Jersey. A linear relationship between air temperature and displacements at bridge joints, as well as the practical independence of those displacements from all other environmental factors, is thoroughly established. New insight is provided concerning the assumption of proper coefficients of thermal expansion. The effectiveness of bridge bearing systems in controlling the movements is discussed. The effects of geometry upon joint displacements are brought to light and the significance of the information with regard to selection of type of joint is pointed out. /FHWA/
