     the present paper studies the effect of various factors on the buckling behaviour and load carrying capacity of the steel arch truss bridges. over three hundred fifty arch trusses are modelled, in abaqus 6.10.1, and the efficiency of truss pattern, boundary condition, connection type, deck level, rise-to-span ratio, truss depth and the arrangement of the hangers are investigated. all of these parameters significantly affect the buckling behaviour of arch trusses. inclusion of web elements in the radial direction, together with web bracings, significantly increases the capacity of the arch trusses. however, the rigidly jointed arch trusses (with only radial web elements), have poor capacity. having double supports (for both top and bottom chords) nearly doubles the capacity of the arch. position of the deck in half-through type bridges, at ½ height of the arch, results in more pronounced effect on increasing its strength. taking into account the material nonlinearity in addition to the geometric nonlinearity dramatically decreases the load carrying capacity of the arch trusses.
