（湖南大學土木工程學院 長沙 410082）[提要] 作者近幾年來完成了19塊冷軋帶肋鋼筋預應力混凝土空心板的試驗，對混凝土拉應力限制系數進行了研究。介紹了這些試驗及研究結果，給出了冷軋帶肋鋼筋預應力混凝土空心板中混凝土拉應力限制系數的建議值。
[關鍵詞] 冷軋帶肋鋼筋 預應力 空心板 拉應力限制系數 研究Authors have tested nineteen prestressed hollow-core slabs reinforced with cold-rolled ribbed steel wires and bars. Restrictive coefficient of tensioristress in concrete was studied. Results of the test and theoretical researches are introduced and the values of restrictive coefficient of tension stress in concrete for design of the slabs are suggested.
