used artificial neural networks to analyze two truss bridges. They conclude that the proposed method accurately locates deterioration in bridge joints [6]. Abdellah used SAP 2000 to create a Warren truss bridge model and found that when the design was complete, the selected sizes and stress ...
From the table,out of plane stability capacity could be calculated convenient according to the spring stiffness. Numerical examples shows that table lookup method is simple and feasible,can be applied in actual engineering design. 展开 关键词: planar tubular truss compression chord members stability ...
It should be noted that the aforementioned studies mainly focus on single joint, while the research on the performance of overall truss is very limited on joints with and without hidden welds. On other hand, steel tubular trusses made of circular hollow section (CHS) members usually fail due ...
a half outer sleeve on each joint and filling concrete into the chord members can effectively improve the load carrying capacity and stiffness of the truss, thus reducing the overall deformation of the truss, but the reinforcing method of filling concrete into the chord members is more efficient....
