Prestressed concrete ridged-frame bridges "PC ridged-frame bridges" and PC long-span bridges such as PC continuous girders are often used at intersections such as rivers and roads, and PC long-span bridges are particularly susceptible to long-term deflection. PC long span bridges are particularly susceptible to long-term deflection, especially in the case of direct-connected track. In this study, a frame analysis model using beam elements was applied to a PC ridged-frame bridge that was designed and constructed, to understand the behavior of long-term deflection and to identify a structural type that is less prone to long-term deflection.
