Abstract This paper presents a new series of thin-walled pre-stressed concrete roof and floor slabs. For roof structures, an innovative thin-walled slab with a larger span, called the wild-goose-shaped slab, has been developed and used in China since 1979. Its use

Four composite joint specimens consisted of concrete-encased steel beams and concrete-encased concrete-filled steel tube (CFST) columns were tested under lateral cyclic loading, in which three specimens were prestressed and the other was not. In the tests, crack distributions and failure modes of the joint specimens were acquired, and the energy dissipation, rigidity degeneration, ductility

Therefore, they can be used to replace the steel bars and prestressed steel bars in concrete structures and steel plates externally bonded to concrete for reinforcement. Since the 1960s, through research and development and engineering pilot projects, FRPs have been used in the construction, reconstruction, and reinforcement of bridges and buildings in the United States (US), Canada, Europe

Its main theme is the repair and retrofit of un-reinforced, reinforced and prestressed concrete structures using carbon, glass and other high strength fibre composites. In the case of beams, the focus is on their strengthening for flexure and shear or their stiffening.
Prestressed concrete sleepers (or railroad ties) are the crosstie beam support in railway track systems. They are designed and constructed under flexural constraints in order to carry and transfer the dynamic wheel loads from the rails to the ground. Under perfect
Sensors 2017, 17, 2239 2 of 14 post-tensioning tendon ducts in prestressed concrete structures, there are non-destructive evaluation (NDE) and structural health monitoring (SHM) methods for monitoring grouting quality or defects. Ultrasonic imaging methods have

constructed from 1980 in China. Almost all of the arches are fixed. Spandrel structures usually are reinforced concrete ones, i.e., reinforced concrete spandrel columns, simple deck reinforced or prestressed concrete girders or spandrel arches. Many of the deck
Nonlinear numerical analysis of the structural behaviour of prestressed steel reinforced concrete (PSRC) beams was carried out by using finite element analysis software ABAQUS. By comparing the load-deformation curves, the rationality and reliability of the finite element model have been confirmed; moreover, the changes of the beam stiffness and stress in the forcing process and the ultimate
Prestressed concrete box girder bridges are widely used because of their excellent properties, such as low cost and aesthetic appearance , , , . A parabolic or circular curve gradient, similar to arranged prestressed strands, is usually adopted for the height of the cross section of this type of bridge to optimize the structural size and cantilever construction  ,  .
