Utilizing robustness,fault toleration and generalization ability of neural network,three different neural networks were established to evaluate the localization and quantification of the plane steel truss damage.

By using sequence uncontrained minimization technique and having costs of steel trusses as objective functions,we optimized the computational models of plane steel trusses and plane prestressed steel trusses with parallel cords.

To begin with practical designing and according to the current national criterion, the static analysis of a plane steel truss is made by means of the direct rigidity array method.

Review and analysis of researches on bending behavior of welded joint of steel tube truss;

Based on considering seven types of load combination,static performance of roof structure with steel tube truss of one gymnasium was analyzed.

A great many intersecting lines exist among steel tube truss structure but the traditional manual-lofting cut can no longer fulfill the requirement for precision and mass production.

The pipe truss of the weather shed is constructed above the railway station platform and it is quite difficult for its construction,as the normal flow of the railway and safety of passengers and construction workers should all be guaranteed.
