Abstract: The general situation of an advertising board with the height of 60m and the length of 180m which built by high-rise lattice column was briefly introduced. Considering the showing effect and the use of function, a lot of works to pursue the best economic indicators have done. Two structure calculation software 3D3S and SAP2000 were used in design process, horizontal comparison were done under different load conditions design different forms of lattice structure column, while increasing set prestressed zipper lattice column design made a longitudinal comparison and select the optimal scheme. It provided a reference for similar engineering in structural form selection.

Keywords: high-rise structure; lattice column; structural form selection; perstressing force; range of experience
