In view of the defects of the current mainstream structural safety analysis method of Truss bridge, the safety analysis method at the component level should be further developed. Therefore, it is necessary to carry out the overall safety analysis and structural optimization at the structural level. Based on the concrete data of the actual steel tru...

... restraint is applied at the two end supports; the load condition is 21kN/m for the whole bridge. From Figure 5, it can be seen that the internal force of the truss is mainly axial force, the upper chord is under compression and the lower chord is under tension, the maximum stress is at the upper side of the span and the stress decreases to both sides, the vertical deflection of the nodes in the middle of the span is the largest. These are consistent with the theoretical analysis and MIDAS analysis results. ...
