چکیده مقاله
In recent years, the use of pedestrian bridges has increased significantly due to theincreasing traffic flow and, consequently, widening of roads and streets Therefore,identifying the most appropriate design according to the current situation is important We know that in addition to the dead load, unexpected loads are applied to the structureof a pedestrian bridge during the period of operation, such as earthquake loads,billboards and finally additional loads caused by accidents of various vehicles whichshould be given more attention to reduce damage and optimally design these types ofstructures In this research, a truss pedestrian bridge designed in SAP 2000 software wassubjected to various loads and the axial, shear and bending forces on the members wereanalyzed In addition, the displacement of structural members under the applied loadshas been calculated and presented The modal analysis of the structure has also beenevaluated The overall results showed that the structural systems of ordinary pedestriantruss bridges have sufficient capacity against static and dynamic loads and, consideringthe weight of the structure, compared to other structural systems in the same conditions,they have lower construction costs As the last result of this research, it can be said thatif the design of the bridge is optimal and the required stiffness is provided, the vibrationfrequency of the structure under pedestrian load, wind load and earthquake load will bewithin the allowable frequency range
