Realistic Cable Modeling in Prestressed Concrete Structures

2022-7-11  In prestressed concrete, cable layout plays vital role in reducing tension from the concrete. Due to curvature cable exerts forces on the concrete to counterbalance the forces causing tension. Cables are laid as a continuous curve but for analysis purpose, they are modeled by some mathematical curve.

Determination of initial cable forces in prestressed

2000-1-1  A single tower prestressed concrete cable-stayed bridge with harp arrangement (example 1). The present method was applied to optimize the bending moments in the bridge deck for the three cases, and the tolerance value used to terminate iterations was 5 kNm. The results for case 3 are shown graphically in Fig. 6, Fig. 7, Fig. 8.

Prestressed concrete - Wikipedia

Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces. Its wide range of application is reflected in its incorporation into the major design codes covering most areas of structural and civil engineering, including buildings, bridges, dams

Sensitivity Analysis of Cable Profile of Prestressed

2022-7-23  Sensitivity Analysis of Cable Profile of Prestressed Concrete Beams The cable profiles for post-tensioning of concrete beams are usually designed as parabolic curves based on the eccentricity of the midpoint of the duct to the neutral axis of the beam. The end points and the midpoint of a duct are very important and sensitive.

Prestressed concrete - Wikipedia

2022-7-11  Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of
