Analysis And Discussion On Seismic Performance Of Steel Reinforce Of Steel Reinforced Concrete Frame Structure

Steel reinforced concrete(SRC) is one form of a composite structure that with steel in concrete, at the same time allocation of longitudinal reinforcement and transverse stirrup. Steel reinforced concrete structures are widely used in modern structure, it has many advantages such as high bearing capacity, deformation capacity, short construction period, high durability, high fire resistance, and greater structural stiffness and damping ratio.When the frame structure with more layers and more complex structure, the axial pressure of the columns is very large. If the reinforced concrete columns are still used,the axial compression ratio will lead to the design of the column cross section. The steel reinforced concrete structure is used in the form can be used SRC girder-RC column and RC column-SRC girder or SRC column-SRC girder. In this paper we use SRC column-RC girder structure, with eight story frame structure as the basic model, total build three kinds of structure models, also set up another modal with four layers of the SRC column at the bottom of the and SRC column structure, the analysis of the three kinds of structure in the wave energy dissipation effect, seismic response analysis selects the maximum shear force, inter layer displacement and acceleration, angular displacement between layers of the parameters. Compared with the pure concrete frame structure, the maximum shear force, inter layer displacement and acceleration, angular displacement between layers of each layer of the structure has a decreasing trend, which can effectively improve the seismic performance of the original structure and achieve more ideal seismic effect.In the part of Influence factors of steel reinforced concrete columns,we selected SRC steel ratio and SRC column in the steel section to discussed,the data provide theoretical references for steel reinforced concrete selection and reasonable utilization.
