Secondary Moments of Continuous Prestressed Concrete Beams Using Closed Form Equation
This paper provides practical engineers with an equation to calculate the secondary moments of prestressed concrete continuous beams. Normally the prestressed secondary moments are calculated by deriving it from the net moment and the primary moments. This involves extensive calculations and sometimes complex integration techniques but the proposed equation described in this paper will give the secondary moment directly. The secondary moment calculated using the equation is compared with the secondary moment calculated using various existing methods such as support displacement method, moment distribution method and stiffness method, and also using the structural analysis software STAAD. For the purpose of analysis, two span, three span and four span beams are considered. This equation can be applied to multiple span beams/girders. Finally the equation is used to show the principle of concordant profile where the secondary moments are zero at the intermediate supports.
