Determine the problems formed while design of pre-stressed concrete

Two types of problems are encountered by  the engineer engaged in the design of pre-stressed concrete members. These are normally referred to as  'analysis of  a member'  and  'design of  a member'.  In an analysis problem, determination of various types of  stresses and deformations  is made. These stresses are compared with the strength of  the member (in bending, shear and bond) to ascertain the safely and serviceability of  the structural member. In a design problem, selection and proportioning of an appropriate shape and size of  the member is done so  that the member is in a position to bear the stresses produced due to the application of loads. Provision of  reinforcement for reinforced concrete members, reinforcement and tendons for pre-stressed concrete members and suitable connections for steel members is to be made afterwards. Subsequent to the design of  a structural member, one has to once again analyse the designed section to confirm the safety of  the structural member.
