摘要：

A steel-glulam hybrid reticulated shell structure is adopted in the Chongming Natatorium. Based on the analysis of the mechanical properties of glulam and the static force of the natatorium structure, the reasonable application range of steel and glulam for the reticulated roof is calculated. Then, the effect of the stiffness of steel splint-timber structure connection node on the overall stiffness of the structure is discussed, and the actual stiffness of the node is obtained by node experiments. Referring to "Technical Specification for Spatial Reticulated Structures" on the stability analysis and ultimate bearing capacity calculation method of the reticulated shell structure, due to the material defects and non-plastic development capacity of the timber, the safety factor of elasto-plastic ultimate bearing capacity for the steel-timber hybrid reticulated shell structure is recommended to be 4.2. © 2021, Editorial Department of Journal of Tongji University.
