| Sumario: | In our country, concrete is commonly used for the construction of bridges deck. But the Heavy weight of concrete decks and the impossibility of making them as long-span bridges deck has caused the engineers to think a new material that besides lightness and ease of implementation can provide a good resistance against applied loads including both dead loads and dynamic loads caused by the passage of motor vehicles and also it causes to accelerate the projects implementation in compared with the specimens has made by concrete materials. Space structures due to the lightness, ease and speed of implementation, are considered a suitable replacement for deck bridges. Since the variations of members diameter and thickness can affect the behavior of structures and deflection due to dead and moving loads, so choosing an appropriate diameter and thickness for each member, in addition to impact on structures behavior and deflection of dead and moving loads, this factor has a major impact on buckling of members. Therefore, in this study by changing the member diameter, are investigate the behavior of bridges deck built with spatial structures. |
