METHOD AND DEVICE FOR OPTIMALLY MODELING LONG-SPAN BRIDGE TO REVIEW FEASIBILITY STUDY

摘要

Disclosed are a method and a device for optimally modelling long-span bridge to review feasibility study on the long-span bridge, capable of reasonably calculating quantities and price to review the feasibility study on the long-span bridge. According to the present invention, the method for optimally modelling the long-span bridge includes the steps of: (a) inputting the expected number of lanes and the expected type of the lanes for the reinforcement of a target long-span bridge for the feasibility study, and inputting an expected main span length of the target long-span bridge; (b) determining final reinforcement type proposed cross section based on reinforcement type cross section specification of match cases where reinforcement matched to the expected number of lanes and expected type is applied, a trend cross section matched to the expected main span length, and a trend geometrical moment of inertia, which are obtained from a long-span bridge design information database storing design information on a plurality of previously-designed long-span bridges; and (c) determining a finally suggested pylon specification, based on cross sectional outline specification of the pylon of the matching cases, a trend effective cross section matched with the expected main span length, and the trend geometrical moment of inertia, which are obtained from the long-span bridge design information database.;COPYRIGHT KIPO 2016
