International Journal of Concrete Structures and …

A computer program, RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), is used to analyze reinforced concrete and prestressed concrete structures. Tensile, compressive and shear models of cracked concrete and models of reinforcing and prestressing steel were used to account for the material nonlinearity of reinforced concrete and prestressed concrete.

Bars made of composite fiber reinforced polymers (FRP) are becoming more popular in prestressing concrete structures. Using FRP bars is an approach to avoid corrosion problems, which are encountered in concrete structures reinforced with conventional steel, especially when built in hostile environments. It also takes advantage of the high strength of the fibers. The variations in the

Piling (Load Bearing) : Piling (Load-Bearing) : Concrete Tech

The outstanding performance and durability of prestressed concrete Piling is well documented in the construction industry. With excellent resistance to bearing and bending loads, exceptional durability, and lower initial cost and long-term maintenance, prestressed concrete Piles will continue to be the first choice in deep foundation materials.

Reinforcement Effect of Inclined Prestressed Concrete …

The eankment slope is vulnerable to slip and collapse, when prestressed concrete pipe (PCP) piles are used to reinforce the inclined soft foundation to bear the load of the eankment. Accordingly, this study puts forward new programs for strengthening eankment foundation with inclined, rather than vertical, PCP piles. Based on an actual engineering accident with eankment slope collapse
