Abstract: This paper conducts the study to investigate the in-plane and out-of-plane buckling of tied-arch bridge. Several analytical models of tied arch with varying span to height ratio and hanger numbers are studied. It has been shown from results that the recommended values of European standards (Eurocode 3: 1993-2) for predicting the in-plane and out-of-plane buckling length factor of tied arch bridges is not rational and often leads to unsafe design. The in-plane buckling length factor not only depends on the stiffness of main arch girders but also depends on the stiffness of deck and vertical ties. Furthermore, it is difficult to predict the first mode of buckling, It largely depends on the effectiveness of a bracing system. To predict the actual critical buckling force it is of paramount importance to know the first buckling mode. In last it is concluded that tied arches are complex structures owing to its various parameters which are difficult to formulate in terms of codal procedures, Therefore more emphasis should be given in actual modeling
