摘要
Abstract
In order to optimize the design of prefabricated reinforced concrete columns,four kinds of reinforced concrete column specimens were designed in this paper,and the effects of different coaxial pressure ratios and connection methods on the seismic resistance of prefabricated reinforced concrete columns were tested.The test results show that the yield load of the assembled column with expanded straight thread sleeve is 42%higher than that of the cast-in-place specimen under the same coaxial pressure ratio.The yield load of the assembled column with rolled straight thread sleeve and grouting sleeve decreases slightly.With the increase of axial compression ratio,the load-bearing performance of the assembled members is improved,and the ductility performance is similar.The stiffness of all specimens decreases rapidly first,then slowly,and then becomes stable with the displacement amplitude.In short,compared with cast-in-place concrete columns,the load-bearing characteristics of prefabricated reinforced concrete columns are improved,and the seismic performance of the two connection modes is not very different.关键词
