高强钢筋活性粉末混凝土梁的抗剪承载力试验
Experimental Study on Shear Capacity of High Strength Reinforced Reactive Powder Concrete Beam
摘要
Abstract
In order to study the influence of shear span ratio,stirrup ratio and longitudinal reinforcement ratio on the shear capacity,8 rectangular simple beams of high strength reinforced reactive powder concrete (HSRRPC) were investigated.The results show that damage form of HSRRPC beams is similar to normal reinforced concrete beams,the co-work between high strength steel and reactive powder concrete is benign;for the beam without stirrups,with the increase of shear span ratio,shear capacity reduces;with the increase of longitudinal reinforcement ratio,the shear capacity improves slightly,but deformation capacity reduces.The calculation value of HSRRPC shear capacity by GB 50010-2010 Concrete Structure Design Code is less than the experimental one,which shows that the code calculation is conservative.The shear capacity calculation formula of HSRRPC is proposed,which makes the theoretical calculation result more close to the experimental value.关键词
