Abstract:A series of  tests on the bending, compressive, tensile capacity of the nodes of temporary assembly grandstand were carried out. The mechanical properties were discussed. Its ultimate bearing capacity, failure mode and load displacement curves of the nodes were obtained. On this basis, a simplified calculation model of the node was given. By comparing finite element analysis with load tests on trellis columns, the accuracy of the simplified model of the node was verified.

Keywords:temporary assembly grandstand; fabricated bolt scaffold; node model; test
