Abstract: Orthogonal and diagnal cassette structural system of assembled overall spatial steel grid was introduced in the application of a practical project. The normal steel frame structural system and the new system were compared of the aspects of the period, displacement ratio, story drift angle, designed bending moment of the beam, floor elastic-deflection and economic performance. The results show that the new structural system has better mechanical properties and economy performance compared with the normal steel frame structural system. The new system can fulfill relevant requirements of multi-storey large-span industrial buildings, which provides reference for the application of the orthogonal and diagnal cassette structural system in the large-span structural design in the future.

Keywords: cassette structure; spatial steel grid; orthogonal and diagnal; multi-storey large-span
