Tall reinforced concrete building in the lower floors column due to axial compression ratio limit, the column cross-section is generally larger, often poor seismic performance of short columns. As we all know, steel reinforced concrete structure (Steel Reinforced Concrete, abbreviation SRC) has a high bearing capacity, stiffness and seismic performance. To this end, the SRC column is introduced into the lower floors of high-rise buildings such can be overcome Reinforced Concrete (Reinforced Concrete abbreviation RC) column section size is too large, the disadvantage of poor seismic performance. The upper floors of the column is still using the RC column, to form the lower part of the the SRC columns at RC column vertical hybrid structure. SRC-RC vertical hybrid structure is a new structure type, more and more foreign high-rise buildings in the structure type, especially in Japan, its application has been more extensive, research also has considerable depth. SRC-RC vertical hybrid structure in the country has produced engineering applications, but its work has not yet commenced, mostly referring to foreign research results, which have not meet the needs of the domestic engineering applications. SRC-RC vertical hybrid structure of key component parts of the lower part of the the SRC structure up RC structure conversion buffer layer, transition layer design improper easy to form weak layers bearing capacity and stiffness mutation, which severely damaged in the earthquake transition layer caused the total destruction of the structure. SRC-RC transfer columns is a critical component of the SRC-RC vertical hybrid structures. The mechanical properties of SRC-RC transfer columns have an important impact on the buffer layer and the whole SRC-RC vertical hybrid force performance. To this end, the launch of an experimental and theoretical study of SRC-RC transfer columns have the important engineering practical significance. This paper studies the different structural measures converting column seismic performance of SRC-RC section steel truncated at the stirrups encryption involves structural measures, the column full-length stirrups encryption, in section steel truncated at the stirrups encryption based on longitudinal reinforcement to strengthen plus pegs plus X tendons. This article by a reinforced concrete columns and seven different structural measures SRC-RC transfer columns of low cycle repeated load test, SRC-RC transfer columns in pressure, bending, shear failure pattern under the joint action of the hysteresis curve attenuation law of skeleton curve, energy consumption indicators, strength and ductility index. According to the test results, the seismic performance of different structural measures SRC-RC transfer columns comparative analysis of the results of the analysis provide a reference for determining the SRC-RC conversion pillar structure measures. Finally, on the basis of the test results and analysis of SRC-RC transfer columns restoring force model, seismic studies provide a reference for the SRC-RC transfer columns.
