AB - Timberconcrete composite (TCC) bridges represent an attractive structural system due to the synergistic use of wood and reinforcedconcrete. However, the benefits of TCC bridges can be hampered by their relatively large flexibility that limits their application to long spans. This paper presents an alternative solution for TCC bridges that incorporates posttensioned underdeck tendons. These steel tendons are deviated by two struts and anchored to the cross beams at the support section, effectively subdividing the total span of the TCC bridge into three subspans. The advantages of the newly proposed system are evaluated for 60 m span TCC bridges. This paper shows that the incorporation of underdeck posttensioning effectively changes the critical limit states governing the design of TCC bridges. In addition, the application of posttensioned tendons leads to a significant increase in the allowable slenderness and efficiency of structures.
