For the two-span parking structure beam with dimensions, material properties and loads shown below, find the following: Determine the prestressing force & drape in both spans. Balance approximately 70% of the concrete load in each span and provide a minimum of 250 psi average compression. Verify that all ACI 318 Code allowable service flexural stresses are satisfied. Design the negative moment non-prestressed reinforcement at the interior support. Show all secondary support reactions. Use the Ven equation (ACI 22.5.6.2) only and determine the required spacing of #3 stirrups (2 legs) at the Span 1 side of the interior support.
