预应力CFRP板加固钢筋混凝土双向板的正截面抗弯承载力
Cross-Section Flexural Capacity of RC Two-Way Slabs Reinforced with Pre-Stressed CFRP Plates
摘要
Abstract
Six of the same specifications as the reinforced concrete ( RC) slab are produced (4 prestressed carbon fiber board reinforced concrete slabs, a non-prestressed fiberboard reinforced RC two-way slabs and a comparative test board reinforcement) in load test, to study the flexural capacity of the prestressed carbon strengthened RC two-way slabs. The results show that; the non-prestressed strengthened RC two-way slabs, the prestressed reinforced RC slabs its unit and ultimate load compared with the unreinforced contrast board and non-prestressed fibreboard reinforcement ultimate its bearing capacity of RC slabs, have big improvement. The reinforcement effect of the prestressed carbon reinforcement method is more obvious, and utilization of the strength of the carbon fiber is higher. When the prestressed reinforcement plate sheet has smaller spacing unit width, the flexural capacity is increased significantly. Compared with the contrast plate it significantly improves the structures anti -bending strength and stiffness, the theoretical calculations match with the experimental values .关键词
