冷轧带肋预应力砼空心板承载力试验研究郭乐工刘忠王王延军１概述冷轧带肋钢筋是一种新型高效建筑钢筋，具有强度高，延性好，与粘结锚固性能优良优点，用于预应力空心板代替冷拔低碳钢丝，每Ｍ３砼可节省５０ｋｇ水泥，显著改善板的工作性能，有着明显的经济、社会效益，... Experimental study on bearing capacity of cold-rolled ribbed pre-stressed concrete hollow slab GUO Le-gong, LIU Zhong-wang, WANG Yan-jun 1 Introduction Cold-rolled ribbed steel bar is a new type of high-efficiency building reinforcement with advantages of high strength, good ductility, and excellent adhesion and anchorage performance. Prestressed hollow slab instead of cold-drawn low-carbon steel wire can save 50kg of cement per M3 crucible, significantly improving the work performance of the panel, and has obvious economic and social benefits....
