Experimental and numerical simulations of prestressed Self-Consolidating-Concrete structures subjected to non-linear deformations

摘要

This paper presents experimental and numerical simulations for investigating the flexural behaviour of five prestressed Self-Consolidating-Concrete (SCC) members subjected to non-linear deformations. In this study, flowable and non-segregating SCC was used for relief of steel congestion among the prestressed concrete members. The members consisted of four reduced-scale beams with and without steel fibres, and a full-scale Type-II AASHTO bridge girder. A total of four three-point and one four-point loading tests were performed in laboratory conditions and simulated using non-linear 2D and 3D finite element analyses. The investigation results provided a quantitative measure of the reliability of the implemented theoretical models.
