Research Of Force Performance On Recycled Aggregate Concrete Short Column With Waste Steel Fiber And Rubber

Along with the tide of reform and opening, Various industries in China are in the rapid development, especially the development of the construction industry and the automotive industry. However, along with the attendant waste concrete and waste tire has also become a serious environmental problem. Scholars are very concerned about how to deal with these industrial garbage reasonable.This paper tests the ordinary concrete as recycled coarse aggregate replacement rate (30%,60%), the scrap steel fiber rubber content (2%,5%,8%), eccentric distance (0mm,50mm,110mm) three parameter as a variable, making a total of12concrete short columns, Which an ordinary concrete short columns, three concrete short columns with scrap rubber and steel fiber, eight recycled concrete short columns with scrap rubber and steel fiber. Pouring in pouring each column at the same time also three150mm×150mm×150mm standard test cubes and three Φ150×300mm cylinder test block. The main work is as follows:(1) Finished12concrete short columns under compression, Analyzed the recycled concrete short columns with scrap rubber and steel fiber about the section failure morphology and the lateral deformation characteristics, at the same time to explore the applicability of the plane section assumption.(2) Analyzed the influencing factors of eccentric compression bearing capacity about the recycled concrete short columns with scrap rubber and steel fiber. Explored the applicability of the compressive carrying capacity formula in concrete specification in the recycled concrete short columns with scrap rubber and steel fiber.(3) Analyzed he recycled concrete short columns with scrap rubber and steel fiber on the experimental basis, using the finite element software ABAQUS. Compared the finite element analysis and experimental results.
