（東南大學土木工程學院 南京 210096）[提要] 板片空間結(jié)構(gòu)體系中板片與骨架或板片之間是由有限個點連接的，連接點之間的板桿間存在縫隙。將點對接觸算法用于該體系的板桿共同工作分析，該算法模型能很好地反映該體系的實際工作狀態(tài)，用于板片空間結(jié)構(gòu)連接設計分析能夠取得良好的效果，并可作為該體系連接設計簡化方法的理論依據(jù)。
[關(guān)鍵詞] 板片空間結(jié)構(gòu)體系 點對接觸 共同工作 連接件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
