Determine Feasibility and Efficacy of Hollow Precast Straddle Bents

Contractors have recently shown keen interest in utilizing hollow precast straddle bent concepts in major Texas Department of Transportation (TxDOT) projects. These contractor-proposed concepts come with multiple benefits, such as reduced weight, improved transportability, efficient erection procedures, cost-effectiveness, and minimized potential for disrupting traffic. However, there is currently a knowledge gap regarding the in-service performance and durability of these elements. Consequently, TxDOT has reservations regarding the service and ultimate load behavior of these concepts, primarily due to the lack of well-defined design criteria and proven structural performance. TxDOT aims to establish clear design criteria and ensure proven structural performance in this context.
