I. Project Overview The Shanghai Jiaotong University Ocean Engineering Laboratory is a complex multifunctional laboratory. The building has a length of 47.50m and a width of 40.95m. The truss adopts a square-angled conical ball node grid. It is designed and constructed by the state designated production company Suzhou Construction and Fittings Engineering Company, and installed by the structural installation engineering office of Shanghai Mechanical Construction Company. Shanghai No. 4 Construction Co., Ltd. designed and erected installation support frames at five locations, and the project was undertaken by the three parties. The structure of the grid consists of the lower chord ball, the horizontal abdominal rod, the diagonal rod, the upper chord ball, the horizontal abdominal rod and the bearing. The net frame length is 147.25m, the width is 40.95m, and the height is 3.150m. The total weight is 50,000kg (see Figure 1).
