Cast Steel Joint

For the cast-steel joint of large span roof system, the main difficulties of prototype stress test encountered are the large scale of the structure system, large loading system and large supporting system, etc. The hydraulic jack of high tonnage is adopted to apply the load. The frame structure of channel steel is used to fix the cast-steel joint and the loading system. The reverse loading system is elaborated to simulate the axial tensile force. So prototype stress test on the cast-steel joint of large span roof system is accomplished successfully. The test results show that, under the designing load condition, cast-steel joint is in a linear elastic state, the structure is globally safe; the maximum surface stress of cast-steel joint is adjacent to the crossing point of steel pipes; the stress value of test is well coincident with one of finite element analysis. This test device system is especially suitable for the stress state test of large components, and can also provide important reference to the similar projects.

Cast Steel Joint

The tree-like structure is a branch of space bionic structures,belonging to the Bionic Architectural Structures. Cast-steel joints with branches are the keys to build the tree-like structures.They are used widely,and the most common joints in our projects are cast-steel joints with two、three and four branches. The cast-steel joints with two branches are planar,while the joints with three and four branches are spatial.Until now,the basic theoretical researches about the cast-steel joints with branches are also relatively scarce.This paper did researches about mechanical properties, calculation methods and structural optimization of the cast-steel joints with three branches deeply and systematically. The result shows that the bending moment has a big influence on the value of the max stress. And the three main failure modes of the cast-steel joint with three branches are yield of the main tubular along the axial direction, local buckling at the connection of the main tubular and branches, and the tearing out of the branches.
