This study looks at the behavior of transverse joints in precast deck panel systems that are used in the construction of bridge decks. An extensive background provides information on the types of transverse joints commonly used by different Midwest state departments of transportation, discussions on the mechanical behavior and failure modes of the transverse joints, and applicable code provisions. SAP 2000 and Ansys 6.1 were used to carry out a finite element analysis to investigate the cause cracking in transverse joints, as well as to provide solutions to prevent this cracking from occurring. The cracking was caused by temperature loadings that produced large longitudinal membrane tensile stresses in the bridge deck. Providing post-tensioning or providing expansion joints at alternate piers in bridges containing precast bridge deck panels were two solution methods that eliminate the cracking in the transverse joints for the conditions investigated.
