    Huang Yong, Wu Jing

Abstract: The steel amount of the grid structure in roof construction of monolayer factory building in shipbuilding industry for different span length was analyzed. The influence of the lattice size and the height of grid structure to the steel amount was also analyzed. The comparison with continuous grid structure and single grid structure was executed. The economic advantage of continuous grid structure was expatiated in detail.
Keywords: the size of the lattice; the height of grid structure; continuous grid structure; economic analysis
