Construction technology of large-span steel pipe truss;

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.

Based on FEA software ANSYS,26 two-span continuous square steel-pipe truss models with hinge joints or rigid joints are presented,the distributions of secondary stress and the influences on the mechenical behavior of total structure are analysed.

In this article, the emphasis is put on the theoretical study about the secondary stress of square steel-pipe truss.

A static test program on two trusses which include directly welded gap K-joints is carried out, the aim of the work is to study the static behavior of the directly welded SHS truss.

In this article,authors monitor and analyze the deformation of a large-span steel-pipe arch truss gymnasium during construction.
