[提要]  板片空间结构体系中板片与骨架或板片之间是由有限个点连接的，连接点之间的板杆间存在缝隙。将点对接触算法用于该体系的板杆共同工作分析，该算法模型能很好地反映该体系的实际工作状态，用于板片空间结构连接设计分析能够取得良好的效果，并可作为该体系连接设计简化方法的理论依据。

In the sheet spatial structure system, as a rule, the sheets and the frame are joined together by welding or special nails, so the spaces or gaps probably exist in the joints. The algorithm of Lagrange Multiplier is used to solve the interactive problem. It can simulate the interactive problem exactly. Finally, by applying it to the design of sheet spatial structure, we have attained satisfying results.
Keywords: sheet spatial structure system; node pair contact; interactive; connector
