Structural Behavior of Prestressed Beams Made With Self-consolidating Concrete
[摘要]

Self-consolidating concrete (5CC) offers ecological and economic advantages over conventional concrete, especially for the precast concrete industry. Besides proper mixture proportioning and manufacturing procedures, the mechanical characteristics of 5CC and its effects on a member’s structural behavior are of particular interest to ensure efficient application. Numerous material models for the  fresh and hardened 5CC are available, but its structural behavior has not been fully described. Although previous investigations 1showed that the characteristics of 5CC do not affect a member’s bending  capacity, SCC’s influence on bond strength and shear capacity is not completely understood. Therefore, tests on the bond strength and shear capacity of members made with 5CC have been performed. The target was to collect missing information on the structural behavior of members made from 5CC and to allow an economical and reliable design of prestressed concrete beams.
