Reinforced concrete special structure in the applications on the basis of the special-shaped column structure , combining the advantages of steel reinforced concrete structure the emergence of a new type of structure . Compared with ordinary shaped columns with high bearing capacity , ductility , seismic performance , excellent features ; compared with ordinary concrete structures with applicable beautiful room utilization high . In this paper, three reinforced concrete L - shaped column and an ordinary reinforced concrete L-shaped cross - section column low cycle loading tests repeatedly reinforced concrete L - shaped column pressure , bending , shear failure pattern under the joint action . According to the test , and analysis of the ductility of reinforced concrete special , hysteretic behavior , energy dissipation capacity , carrying capacity degradation and stiffness degradation characteristics . ANSYS software to numerical simulation analysis of reinforced concrete L - shaped column . From the load - deformation curve to compare the ANSYS calculation and the experimental values ??. The results showed that the the ANSYS calculation results with the experimental results agree well . Axial compression ratio , shear span ratio , stirrup ratio on the ductility of reinforced concrete special , and reinforced concrete special with the bearing capacity and deformation capacity of reinforced concrete columns were compared . The test results show that the reinforced concrete special high capacity , good ductility , better than its seismic performance of reinforced concrete columns . SRC Reinforced Concrete Columns restoring force model . Finally, the reinforced concrete L - shaped column of the yield curvature and biaxial eccentric compression normal section bearing capacity calculation methods are discussed . Through the test , the main conclusions are: ( 1 ) reinforced concrete special carrying capacity increased with the increase of the amount of steel . (2) the increase of the ductility of steel reinforced concrete columns with steel output increased, decreased with increasing axial compression ratio . ( 3 ) reinforced concrete special shaped reinforced concrete columns , high capacity , good ductility , energy dissipation capacity and deformation capacity seismic performance excellent .
