[提要] 依據(jù)幾個大跨度單層門式剛架輕型房屋的設(shè)計體會，對支撐體系的設(shè)計，著重對支撐體系的剛度、承載力、連接進行了分析和研究。同時就支撐體系的設(shè)計要點提出了建議。
[關(guān)鍵詞] 圓鋼十字支撐 剛度 變形Through the design of huge span rigid frames recently, the bracing system and detail are discussed, especially about calculation of the bracing connection and local deformation. Types of failure included tearing of welds and web are described. The behavior and stiffness of the bracing are analyzed. Based on the experience of several projects, the key points of the design suggestions on bracing system are proposed.
Keywords: steel structure; rigid frame; diagonal rod brace; stiffness; deformation
