Abstract
According to the common cracking phenomenon of steel-concrete composite wall structure in current engineering and there are still few researches on the shrinkage deformation of concrete under the restriction of the stud, based on this realities, a study on the constraints of high-strength concrete shrinkage stress of the stud was carried out.In this paper, the improved test method of reinforcement inner restraint is used to study the shrinkage of high-strength concrete under the constraints of bolt-nails and is also used to analyze of different types of stud constraints in high strength concrete shrinkage. Through orthogonal test, this paper also discusses the different combination of factors and the optimal combination of the inner constraint intensity.At the same time, through establishment of the finite element model,this study analyzes the interaction between stud and high strength concrete,it can pointed out the stress concentrate position, which provides a better distribution of early concrete cracking under the constraint of bolt-nails.关键词
