摘要：

The national financial information building, 360 meters in height, is a key project in Beijing, in which there is a joint switching from a square structure to a circular complex structure at the height of 270, m. According to complex stress condition of the key joint and the limitation of the test lab, an appropriate area was chosen to simplify the number of the forces by which we place suitable number and location of the loaders. The test structure is optimized by using the finite element analysis software ABAQUS. According to the simulation results, the upper concrete filled steel tubular joint effectively improves the stress concentration conversion tectonic area and meets the design requirements and the capacity requirements as well. ©, 2014, Tianjin University.
