Abstract: The large span dry-coal shed adopts a reticulated shell structure with three arcs of different radii in XiangFan power plant. We can confirm the dry-coal shed's structure layout, and the latticed shell's extemal dimensions, supporting, thickness & construction method through optimizing design, which can made very good comprehensive benefit and offer reference for similar projectin the future.
