Aluminum single-layer reticulated shell construction

Ningbo’s first aluminum alloy structural reticulated shell, which is the reticulated roof of the Tangshu School Sports Building in Haishu District, is located at the south of Huancheng South Road and the east of the Nantang River. With its unique oval shape, it looks like The eye-catching pearls are scattered around the corners of the Tang School in the Haishu section, which adds a lot to the beautiful campus.

The structural system of this project is a single-layer reticulated shell, which is supported on the lower concrete structure. The ellipsoidal reticulated shell has a total length of about 51 meters, a total width of about 33 meters, and a structural height of about 20 meters. The integral reticulated shell is supported by 28 embedded support in the lower ring beam.

The ellipsoidal reticulated shells have different heights, different curvatures at different plane positions, curvatures of the gusset plates, diameters, and hole positions. Also, The lengths and angles of the shells are different. This has brought deeper design as well as enhanced production. Due to the huge difficulty encountered in solving problems of large design workload of traditional aluminum alloy plate node single-layer reticulated shells, cumbersome node check calculations, and the deepening of complex lofting, a set of aluminum alloy plate node single-layer reticulated shell design systems based on ANSYS, ABAQUS and ObjectARX platforms were developed.
