摘要：Calculation of the optimum axis shape of the arch bridge is presented using a condition which implies that the bending moment due to dead load is equal to zero in every all arch sections. For a given geometry of the obstacle different types of arch shapes for different arch elevations were calculated. After that, internal forces in the arch and supports forces were calculated by which optimum shape of the arch is determined. Forces were determined on the beam model of the arch using software package SAP2000. The load taken into account was a self-weight of the superstructure that is assumed as a ribbed cross-section with adequate bridge equipment (guard rail, facia, footway, curb, and roadway) and self-weight of arch and arch columns which are assumed to be of a hollow rectangular cross-section. Traffic and other loads didn’t taken into account in preliminary calculations but they are used in further design and based on them axis form is corrected.
