State the Design process of Prestressed Concrete

Most of the times, the design process is an interactive and trial procedure in which the cycle of analysis - design - analysis is followed. For the structure which is to be designed, we have to estimate the loads, consider trial sections for the structure and analyse it for the internal forces and moments etc., induced due to external loads. Then the structure is designed and re-analysed for the induced internal stresses. If these induced stresses exceed material strengths then the design is to be modified. The primary object of structural design is to provide a structure with safety and economy during its entire service life.
