摘要
通混凝土在严寒、腐蚀等特殊环境下的耐久性问题一直是工程研究的热点问题。基于无机聚合物耐高温、耐腐蚀和玄武岩筋高强、耐腐蚀等特性,提出一种全新的结构体系——玄武岩筋无机聚合物混凝土柱。通过有限元软件ABAQUS,构建了玄武岩筋无机聚合物混凝土大偏心受压柱(IPCC-LE,Inorganic Polymer Concrete Column-Large Eccentricity)、玄武岩筋无机聚合物混凝土小偏心受压柱(IPCC-SE,Inorganic Polymer Concrete Column-Small Eccentricity)的有限元计算的模型,通过同试验结果对比,验证有限元应用的可行性;探讨了构件在不同配筋率与偏心距情况下的极限承载力,探究了玄武岩筋无机聚合物混凝土柱的工程适用性。
The durability of ordinary concrete that applies in the special environment such as the cold and corrosive,has always been a hot issue in engineering research.Based on the characteristics of inorganic polymer concrete which has high temperature resistance, high corrosion resistance,basalt reinforcement which has high strength,high corrosion resistance,it presents a new structural system-stub columns of basalt reinforced inorganic polymer concrete.Through the finite element software ABAQUS, themodels of large eccentric com- pressive stub columns of basalt reinforced inorganic polymer concrete （IPCC-LE, inorganic polymer concrete column-large eccentricity ） and small eccentric compressive stub columns of basalt reinforced inorganic polymer concrete （IPCC-SE, inorganic polymer concrete column-small eccentricity ） have been constructed,thus verify the feasibility of the application of finite element.At the same time,the ulti- mate bearing capacity that under different reinforcement ratios and different eccentricity is studied,and the engineering applicability of IPCC is explored.
