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.
