【摘要】 作者近几年来完成了 １９块冷轧带肋钢筋预应力混凝土空心板的试验，对混凝土拉应力限制系数进行了研究。介绍了这些试验及研究结果，给出了冷轧带肋钢筋预应力混凝土空心板中混凝土拉应力限制系数的建议值。更多还原

【Abstract】 Authors have tested nineteen prestressed hollow-core slabs reinforced with cold-rolled ribbed steel wires and bars. Restrictive coefficient of tension-stress 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.更多还原
