Abstract: Project of the single building F2-1 which is located in the Xishan AF-area was introduced, the dynanuc characteristics were analyzed, and the main internal force and displacement response of the structure based on multiple load combination were discussed. The advantage was understood when the steel truss is applied in a cantilever structure, and the design of the joint for the steel truss was introduced.
Keywords: steel truss; cantilever structure; joint design; damping ratio
