[提要]  针对应用于空间结构的铸钢节点形式和特点，比较了贯通式和非贯通式节点的力学性能，结果表明非贯通式节点具有较好的力学性能。提出铸钢节点设计原则和保证强度可靠的标准节点构造确定流程，并以非贯通式十字型铸钢节点为例加以说明。
[关键词]  铸钢节点  非贯通式节点  强度设计原则

The style and characteristic of cast steel joints used in space structures are introduced. By comparing of the mechanical properties of penetrated and non-penetrated cast steel joints,the latter shows better behaviors.A stress criteria for design of the joint and the procedure for determination of the shapes and sizes of standard joints are proposed. And a cross-type non-penetrated cast joint is taken as an　example to demonstrate the method suggested.
Keywords: cast steel joint; non-penetrated joint; stress criteria
