The bolt-sphere joint belong to the semi-rigid node, whether it can be applied in the single-layer reticulated shells is one of the key problems which is badly in need of being solved in this field. This paper based on the finite element analysis and took advantage of the results of tests of bolt-sphere joints. The moment-rotation curves of bolt-sphere joints are obtained from, then through introducing the node stiffness simulation of shell into the numerical methods, the analysis method of semi-rigid node net shell were set up. On this basis, specific to citizen fitness center in the north new district of shen yang, which is an 80m diameter reticulated spherical shell with bolt-sphere joints, and the nonlinear stability of the different form during the work progress were analyzed, the skin effect of single-layer reticulated spherical shell with bolt-sphere joints were discussed. The result shows that during construction phase, the bending is the major stress form of the part of the reticulated dome’s bars, which result in the ultimate bearing capacity of 1／2 dome under horizontal load is the lowest, and because of the big deformation of dome’s upside, the ultimate bearing capacity of 3／4 dome under vertical load declines largely. After the dome is closed, the bending bars are transformed into being major suffered with axial force, its ultimate bearing capacity reach the 4.7 times of design load under vertical load and 9.2 times under horizontal load, therefore only to adopt rational measures and avoid the buckling failure during the construction phase,the bolt-sphere joints can be applied into the single-layer reticulated shell.
