Abstract: The objective of this study is to investigate the appropriate optimization method to find minimum weight and the minimum cost of a Railway PSC slabs. In view of achieving this objective it is decided to develop a computer code in MATLAB7. After validating this computer code by comparing the results with analytical results, it is planned to carry out the economical and safe design of PSC slab. For the minimum weight and cost design of the PSC slab unit the following design variables are chosen: 1- Depth of PSC slab unit at center, 2-Depth of PSC slab unit at end, 3-Eccentricity of prestressing cable at center, & 4-Total prestressing force.
Keywords: Prestressed concrete slab, Railway bridges, Structural optimization, Prestressing force, Cost and weight Optimisation.
Scope of the Article: Concrete Engineering
