摘要
通过GFRP筋混凝土板抗弯性能实验,探讨了GFRP筋和钢筋组合作用下混凝土板力学性能。结果表明荷载作用点钢筋先屈服,得到充分的延性,就是利用钢筋混凝土特性得到充分的延性,防止GFRP筋和钢筋组合作用下的脆性破坏。组合构件比纯GFRP构件极限挠度、延性、变形率都得到很大的改善。
Experimental research on bending resistance of GFRP reinforced concrete slab,the mechanical properties of GFRP reinforced concrete slab are discussed. The results show that the reinforcing bar is yielding under the loading point first and the full ductility is obtained,which uses characteristics of reinforced concrete,preventing brittle fracture of GFRP reinforced concrete. The ultimate deflection,ductility and deformation rate of GFRP reinforced concrete are much better than those of pure GFRP members.
