Belitic calcium sulfoaluminate (BCSA) cement is a sustainable alternative to Portland that offers rapid setting characteristics could accelerate throughput in precast concrete operations. BCSA cements have lower carbon footprint, embodied energy, and natural resource consumption than cement. However, these benefits are not often utilized structural members due lack of specifications perceived l...

Abstract The paper is focused on the probabilistic structural assessment of existing prestressed concrete girder bridges accounting for traffic loads. Particularly, this study concerns fragility class characterized by post‐tensioned tendons built in 1960‐1970 period. safety such bridge can be affected construction errors involving voids ducts and degradation conditions terms tendon corrosion wh...

Abstract Owning to good mechanical properties, steel–concrete composite (SCC) and prestressed concrete (PC) box girders are the types of elevated structures used most in urban rail transit. However, their vibro-acoustic differences yet be explored depth, while structure-radiated noise is becoming a main concern noise-sensitive environments. In this work, numerical simulation investigate vibrati...

The elastic foundation beam theory has been widely used in civil engineering, including railway, tunnel, and building foundations. With the development of fabricated structures, more beams need to be prestressed. In order explore frame with anchor-cable slope reinforcement project, this article, prestress is applied both ends beam. Then, according calculation method internal force deformation u...
