The program consists of six pieces of two-span continuous beams with box-section as shown in Fig.1.Considering that the prestressed concrete continuous beams adopted in bridge engineering generally have the varied section,therefore,the height of the test beams is 50 cm and 30 cm for the mid-support and the mid-span section,respectively,and a linear variation of the section height is adopted between the mid-support and the mid-span
section.
The design mix of concrete is determined by trial and error.To improve the workability of concrete,a high-efficiency water-reducing admixture (superplasticizer) is used,and the final mix of concrete is 1:0.35:0.98:2.52:0.012 (cement:water:sand:coarse aggregate:superplasticizer).The steel fiber used in the present study has a shape of hooked-end.The basic material properties of concrete are given in Table 1.The basic material properties of the prestressing
tendon and reinforcement bar are listed in Table 2.
