| Abstract: | The Mandalay Bridge in Myanmar is structurally a rigid arch and flexible girder bridge.During construction of the Bridge,the closing of the side arches was carried out prior to that of the main arch.In the light of the characteristics of the steel girder structure,construction conditions of the Bridge and natural environment where the Bridge is located,the scientific,economic and reliable construction techniques were formulated and the zero error of closing the steel girders of the Bridge was achieved just by adjusting displacement of the girders in three directions without applying external forces.In this paper,the construction techniques for closing the girders are dealt with. |
