Experimental Study on Axial Compression Performance of Light Steel-Steel Fiber Recycled Concrete Composite Short Column
摘要
Abstract
A light steel-steel fiber recycled concrete composite column(SFRC composite column)was proposed.In order to study the axial compression performance of the composite column,five groups of short column specimens with varying configuration were tested,including one group of steel column specimens and four groups of composite column specimens.The effects on the failure characteristics,load-displacement curves,bearing capacity,stiffness and ductility of composite columns were studied with the parameters of section configuration,steel fiber content and recycled concrete strength.The results indicate that the SFRC composite column enhances the stability of the light steel column and substantially increases its bearing capacity.The bearing capacity of SFRC composite column increases with the addition of steel fiber.Steel fiber can restrain the crack development of recycled concrete and reduce the damage and stiffness degradation of specimens.The bearing capacity of composite column increases with the increase of recycled concrete strength,but the ductility decreases accordingly.A formula for calculating the compressive bearing capacity of SFRC composite short column has been established based on the code.关键词
