4ĥ Prestressed Box Girder Design Bridge specification and Cross-Section Bridge type: 3-span continuous PSC Box Bridge (FSM) Bridge length: L = m Bridge width: B = 8.5 m (2 lanes) Skew : 0 (No skew) L OF PIERC L OF PIERC Construction 시공방향 Direction 시공이음부 Construction Joint 시공이음부 Construction Joint RP1 P2 RP2 A1 Fig. Then we will perform PSC section design for the construction stage and the service state. In this tutorial, we first open FSM bridge and add reinforcement. However, these automatically assigned member types to elements can be modified using Modify Member Type function (Path: Design> Common Parameters> Modify member Type). All the elements which are on the X-Y plane are taken as Beam members and those with some inclination to X-Y plane are designated as Column members by midas Civil. PSC section design can be performed for the beam elements only. Construction stage analysis should be performed because PSC section needs to be checked during the construction stage and the service state.
